Fingers of Frost[1] provides mana regeneration + 10% bonus damage upon completion. Frost Shards[4] will multiply your damage against heroes, mercenaries, and minions. Consider Frost Armor[4] for protection against dangerous assassins, or Arcane Intellect[4] for more fuel against tanks. Ice Floes[7] provides maximum value for its tier and high synergy with future talents. Elemental[10] is by and large the more flexible ultimate as it will shine well on every battlefield and composition. Icy Veins[13] is non-negotiable in many scenarios - you'll multiply your E's with Ice Floes + multiply your Qs for multiple enemies hit each. Numbing Blast[16] provides ample CC to your team, and can single handedly kill two+ enemy heroes at once with Icy Veins. You may find Northern Exposure[16] useful if the CC isn't necessary, and that there is a lot of health to chew through. Finally; Wintermute[20] will benefit from Frost Shard piercing, more frequent Ice Floes Cones, Cone rooting or armor shredding, and lastly will copy every ability supercharged in Icy Veins state.

Do you see melee assassins, tanks, and bruisers in 3 or 4 quantity? Pick up a bigger, badder build. Most melee-heavy compositions are extremely vulnerable to the increased slow of Lingering Chill[1]. It's not a mandatory talent - but it often overshadows Fingers of Frost[1] in raw utility. Arcane Intellect[4] is the go-to due to high health bars; you need as much mana as possible. Ice Floes[7] is non-negotiable in the sheer value it provides you. More damage, slowing, and CC from rooting. Water Elemental[10] is a reliable staple, though Ring of Frost has potential value due to how likely they are to clump together and how nasty the root is to them. Icy Veins[13] is incredible with Ice Floes, and will synergize with Numbing Blast[16] to keep an entire team immobilized as you mow them like grass. Northern Exposure[16] deserves a mention -- there is no better opportunity to shred the armor of such beefy targets. But rooting makes melee heroes harmless, so I prefer the safety. Wintermute[20] for the penultimate upgrade to your damage and CC. Honorable mention to Deep Chill[20] to completely cripple the enemy team - if that is important to you.

Are you fighting on Battlefield of Eternity? Is the map 99% macro play and 1% proper team fighting? Is there an extremely annoying Mal'Ganis/Imperius who is shoving their face into you and your mates? Consider this build for additional single target firepower. Q piercing is essential - pick up Fingers of Frost[1] for mana regeneration and damage. Frost Shards[4] is mandatory to multiply your damage against the enemy team and mercenaries. Since all of your damage is frontloaded to your Q, you better make sure it can hit more than one enemy. Ice Lance[7] is the rockstar of this build -- high CDR and refreshment rate against one enemy. You can focus fire them without ever running out of chill time + take out structures and big monsters easier. Water Elemental[10] for added single target damage. Icy Veins[13] is not a strict requirement, but the build does lack a lot of AoE damage, so pick it up to really hammer down on an enemy. Pick your preference for level 16: the root[16] combo is absent, so armor shred[16] is awesome against an overconfident tank. Wintermute[20] is the final pick up to add much needed damage to your combo and obliterate fortifications.

Fighting an unorthodox team of multiple ranged assassins + healer? Well, you no longer have a frontline to abuse Ice Floes on. So you need to match the enemy range capabilities. Pick up Winter's Reach[1] so you can catch enemies out of position and fight them. Frost Shards[4] is amazing with Ice Lance[7] so I heavily lean on to it. Note: you'll run out of mana frequently, but this shouldn't be a big concern vs squishy enemy teams. The important facet of this build is to find a way to chill an enemy, then hit them with an Ice Lance Q. Repeat the Qs until you kill your enemy. Water Elemental[10] is a great chaser and is much more reliable than Ring of Frost. Icy Veins[13] is hard to utilize since these games don't have tanks to ground a fight in. Instead, it's just a lot of short and miniaturized duels, so I find more value off Ice Barrier[13]. But Icy Veins[13] can certainly overwhelm a high priority enemy. Numbing Blast[16] is mandatory for the rare CC effect. If you catch an enemy, they'll likely die to your team. Wintermute[20] for long range mimicry, or consider Ice Blink[20] for safety and outplay potential.

Trust me, I try so hard to make this build work. But it's terrible, it makes you extremely dependent on your tank and whole team, and you don't even deal the same amount of damage as a standard Jaina. But you have wombo-combo potential and strong waveclear to boot. Why aren't you playing Zagara, then? Since you have a lot of range, I like Winter's Reach[1] here. The other options are good if range isn't needed. Then, more mana with Arcane Intellect[4] (if you don't have FoF[1]) or Frost Shards[4] for more waveclear and damage. Icefury Wand[7] provides crucial CDR on the long CD Blizzard, plus additional basic attack damage you should take advantage at every opportunity. Ring of Frost[10] is necessary to help guarantee your Blizzard can deal AoE damage. Next up... sigh Storm Front[13] for more range and radius. Snowstorm[16] for a little more damage (which a single AA can cover mind you). Then, you have the choice of Cold Snap[20] for Ring CDR + roulette on landing on a hapless foe, or Deep Chill[20] to provide the team with more utility since you are a non-hero as is.

[Winter's Reach]
For when you need to match those team compositions with long-range reach. If approaching the enemy team's backliners won't result in immediate death, then you do not need this talent.

[Lingering Chill]
When planning to take Arcane Intelligence at level 4 for when I need an outrageous amount of mana, I'm left with picking up utility or more damage at level 1. Lingering Chill is unbelievably annoying to enemy bruisers that beg to get in range to deal their damage. A 6 second 25% slow feels like an eternity. A longer chill effect also means a longer window of time for you to hit them with your abilities for bonus damage.
This talent is 100% unnecessary. I pick it for the rage inducing factor. Or if I want to do Lingering chill[1] + Deep Chill[20] (+ Frost Armor[4] for the memes) to provide an unbelievable amount of CC for my team.

[Fingers of Frost]
One of my favorites! A very simple, yet useful talent for Jaina. You'd be surprised how much that bonus mana regen helps to keep you afloat throughout the game. Then, you get +10% bonus damage when you complete the quest! Completing your quest as soon as possible is your early game objective. Go to a lane, cast Blizzard , grab the regen orb and go to the next lane. Keep doing this until you're done. A smooth early game will let you finish the quest by level 7. If a more hectic game, then typically level 13, which is right on time for Icy Veins[13].

---

[Frost Shards]
Your Frostbolt now pierces to hit more targets. In most games, you don't quite need unlimited mana, and you don't need the defensive utility of Frost Armor[4]. Frost Shards is the most useful talent in this tier in increasing your damage output in a fight. Say goodbye to your frustrations of landing a pretty strong combo on someone, only to have your Frostbolt hit something meaningless!

[Arcane Intellect]
Infinite mana at your fingertips. Fingers of Frost[1] does a great job giving you mana for all purposes, but not quite enough to sustain minute-long fights. Arcane Intellect is an excellent pick against tanky heroes so you can keep casting abilities without hitting the brakes. The 10% Spell amp is a nifty boost for the initial stages of a fight. Be sure to recall home and replenish to full mana before a fight so you can keep it maintained throughout an objective's duration.
Fingers of Frost[1] in conjunction with, though overkill, will completely solve your mana issues. Not only that - it'll guarantee you stay over the >75% mana threshold for the spell amp, and you'll have Chill bonus damage for a total of +20% damage!

[Frost Armor]
A sleeper talent. I love, love love love Frost Armor. Against melee assassins, or ranged assassins dependent on auto attacking, they're going to want to kill you. At some point in their combo, it will involve auto-attacking. Automatically inflicting a slow helps so much in deterring them away, kind of like having bright vibrant spots to deter predators. The chilled effect can allow you to retaliate in full force - every ability, even the initiator, gets amplified. Hitting a slower target helps accuracy, too.
That 75% armor is splendid against slow, hard hitters. Thrall, Imperius, Ragnaros, Butcher can't do anything to remove the block themselves. This tremendously improves your odds of survival.

It is highly recommended to pick up Numbing Blast[16] at level 16. Got hit? Enemy is chilled. Turn around and cast Cone of Cold -- automatic root and death sentence!

---

[Ice Lance]
A former meta-staple to Jaina gameplay, and a faithful servant for many long years. Flexible, in constant use, and powerful. Unlike Ice Floes[7], where it has a substantially more powerful effect, Icelance[7] activates on any chilled target. Ice Floes only works on enemy Heroes. Hence, Icelance[7] gives Jaina a significant boost in map presence. She can kill any merc camp on her own, take down bosses or huge monster objectives efficiently, and destroy forts without breaking a sweat. Not to mention that she still retains very good teamfight potential. The fact that Frostbolt's CD is less than 4 is critical. You can continuously benefit from hitting a chilled target + reapply it for the next Frostbolt.
Note, it's EXTREMELY recommended to pick up Ice Shards at level 4 if you plan on taking Icelance[7]. If you're casting Frostbolt twice as often, then why shouldn't you double or triple your damage output? Secondly, the piercing effect helps a lot ensuring that no random entities block your Q from hitting a chilled enemy.
The 10 bonus mana you get is a nice touch. It makes up for lack of Arcane Intelligence at level 4, and it ensures that spamming Q isn't the main reason you run out of mana.

[Ice Floes]
An unreasonably over-stated talent. Free CDR on your Cone is awesome! Getting the 2x CDR for hitting chilled enemies is a very easy condition to achieve. There are plenty of opportunities to hit 2+ enemy heroes in almost every enemy team composition. When you do get that -8s CD, you can keep enemies chilled indefinitely. Each wave does withering amounts of damage until they plop over and die.
If you thought this talent was pretty strong, wait until your future levels.

[Icefury Wand]
The most important perk to Blizzard builds. Centering an entire build around a 15 second CD is... not most wise. Being able to cast more blizzards to take advantage of your talents is extremely important. Optimal use of the talent effectively turns the ability into a 5 second cooldown! Also, the bonus damage you get off your auto attacks is nothing to scoff at. Suddenly, you hit as hard as a Raynor! You should auto attack as much as possible since you need more damage to make up for your lack of CDR in other abilities.

If you're not committing to the Blizzard build, Icefury Wand is just a little weak when compared to Icelance[7] or Ice Floes[7]. It's a perfectly fine talent, especially at level 7 right as you pick it up. The real reason it's such an awkward talent is because it is has anti-synergy with Icy Veins[13], the most important Jaina talent. When supercharged by Icy Veins[13], you are constantly casting ability after ability. You literally do not have the time to stop and right click. Furthermore, much of Icy Vein's explosive power is highly reliant on your level 7 talent pick. Ice Floes to devastate swathes of enemies; Icelance[7] to obliterate a single high priority target, or fort. Why should I choose Icefury Wand when pursuing a regular build? Blizzard is just a minor component to combos of most builds. And if I really wanted more single target damage, be it for teamfights or NPC killing, Icelance is does a better job.

---

[Ring of Frost]
In games where both teams engage in huge, heavy teamfights where the formation is relatively stable, you will need some big guns. Ring of Frost will punish enemy teams that clump too close together. Rooting any target not a tank is guaranteed to die to your focus fire. Your team will appreciate the long roots you inflicted as they finish off their foes.

The real power of Ring of Frost is slotting it in alongside a team with huge teamfight ultimates. Yours may take 1.5 seconds to fire off, and hence it is quite hard to land. But if you got set ups and the enemy team is forced into sitting still due to your teammates, then it's easiest thing in the world to land. The subsequent wombo combo will eviscerate entire teams or cleave through a few people without mercy.

[Summon Water Elemental]
Water Elementals from Warcraft 3, my beloved! In our time of need, you return more powerful than anyone can imagine. Elemental is extremely versatile and will work in any situation. A low cooldown, high uptime summon that enables yourself to do a withering amount of damage. If you need more damage, you will take Water Elemental. If you envision getting into a bunch of small skirmishes due to the shape of the map, Elemental is vital. The cooldown's so short you'll have it for every fight and few people can kill it swiftly on their own.

Casting it first and sicking it on an enemy you're about to kill will kickstart your combo hard. First, enemy is slowed so it is easier to land your abilities. Second, EVERYTHING is frost-damage boosted. Thirdly, the Elemental is outputting ~120 damage per second for 20 whole seconds. Do the math. Too late, enemy's dead!

---

[Storm Front]
First of all, I want to write a complaint to every Jaina that picks Storm Front absent mindedly. You have Icy Veins[13] to choose on level 13. PICK THAT INSTEAD! Your talents were looking so fine and then you got... THIS??

Okay. Rant over. Storm Front is an unnecessary talent. It does nothing to help you kill. Extra range on your Blizzard is meaningless when you're not close enough to use your abilities. Remember, the bulk of your damage comes from chaining Frost-amplified spells together. Not sporadic, individual abilities not boosted by Frost. Furthermore, additional radius is nice and all but you're investing a whole talent to increase the odds that your Blizzard hits 2 waves instead of 1. Or maybe you tagged a second person who will move out of the way. You could have achieved the same results with better blizzard placement...

There is only one reason you're getting Storm Front and that's when you have initiator tanks with CC that dive deep to deliver it. Think Diablo, Anub'Arak, Muradin. In this situation, you'll always be able to drop Blizzard on a stunned enemy no matter how far back you are. You can always support your front line and the odds are good you will land all 3 waves on an enemy. That's it! That's the only use-case for this talent. And even then... you can still do exactly that if you were just a bit closer to your tank when he engages an enemy. God I hate this talent's mere existence.

[Ice Barrier]
Here's an actual, useful talent that can benefit Jaina in her deficiencies! Most of her talents have something to do with doing more damage, but this is a rare defensive talent. In games that you are being targeted due to the threat you represent, Ice Barrier gives you that much needed durability.

If your team is communicative and are willing to peel for you, I will happily trade away Ice Barrier for Icy Veins[13]. That's a case where your mates are applying less pressure/damage/CC in the direction of the enemy team in order to protect you. You need to step up a pace to carry for them.

Ice Barrier is entirely dependent on damaging frosted enemies. Any talents that frequently apply Frost ( Water Elemental, Frost Armor[4], Lingering Chill[1]), or reduce the cooldowns of your other abilities ( Ice Wand[7], Ice Floes[7]), will let you retain your massive shielding for a longer period of time.

[Icy Veins]
Behold, Jaina's 2nd heroic ability. The single greatest talent power-up in the entire game, bar none. The enabler of every talent and ability in your arsenal. Say hello to Icy Veins.

I'm here to dispel the notion that just because it's an extra activatable ability means it is difficult to use. Absolutely not. You activate Icy Veins[13] whenever the hell you want in a middle of a battle and you will reap the power of a thousand suns. It's a free Ana boost whenever you command. The only cost you must pay is to smash your keyboard 5x as hard when powered up.

While Icy Vein'd, for every 1 second that passes, all of your basic abilities will cooldown by 3 seconds. Let's do some math, assuming you live and use every ability possible over the 5 second buff duration:

• You will be able to cast ~4.75 Frostbolts. Waiting another half second is trivial, so basically 5 Frostbolts!
• You'll cast Blizzard twice.
• You'll cast 2.5 Cones of Cold. Two full abilities and half cooldown on your third.
• At level 7, you'll have one of two options: If you picked up Icelance[7], you'll fire 7 Frostbolts. If Ice Floes[7], and assuming best case scenario, that's 6 Cones of Cold!
• Combining Ice Floes with Numbing Blast[16], your Cone of Cold is effectively a 0.83s CD for 5 seconds. It will root everyone for 1 second. That's 100% uptime. You can keep blasting away and root everyone for 5 whole seconds!
• Wintermute[20] MIMICS your abilities with full talent properties. Do everything above again at 50% damage.
• Every ability you have is AoE. It can affect the entire enemy team.

Let's set an example. You and enemy team are level 13. You're fighting Azmodan, who has 3,945 Health. He has the 17th highest health in the game, and hence beefiest ranged assassin. Jaina is following the Generalist build, but hasn't completed Fingers of Frost[1] for simplicity. You are not using Water Elemental, and you initiate with your Blizzard .
A full rotation of abilities over Icy Veins[13] duration, including 1 person CDR Ice Floes[7], and two full casts of Blizzard, will deal 5,718 Damage. You just killed him 1.5 times over without even using your ultimate.
In more realistic conditions -- say where you only hit 3/6 waves of Blizzard, miss maybe 2 Frostbolts, but land all Cones because they're easy to hit, you deal 3,817 damage instead. You can easily knock the demon over with one attack. Had you completed Fingers of Frost[1] for +10% Frostbite damage, you'd have done 4,057 Damage.

What if... you found two enemies instead? Azmodan and maybe a stray Anduin. The generalist build includes Frostshards, and we will assume your good positioning is also piercing Anduin with everything you got. Ice Floes[7] now works off 2 person CDR, so let's see these numbers...
Best case scenario == 7,302 Damage on both of them
Realistic scenario == 5,399 Damage
Realistic + Globe talent == 5,746 Damage

This is why I like Ice Floes. It is a very common scenario to tag 2 or 3 people with the huge cone, and then your damage multiplies AND repeats faster. Icelance[7] on the other hand accelerates your single target damage.

You're not throwing some basic rock at someone. You're throwing entire 2003 Grandway Style Pianos at your opponents. You're serving cold plates of DEATH, with a side dish of PAIN.

---

[Snowstorm]
Don't pick Snowstorm.

Anyways, here's the long reason why. Beware! This is a misleading talent. You'd think Blizzard would do exponentially more damage, but no! The increasing damage in waves is additive in respect to the base damage. At level 16, your Blizzard does 255 damage/wave. Assuming chilled target, your waves total damage is:
1.5 * (255 * 3) == 1147 damage.

With Snowstorm as it works...
255 + 127.5 + 0 | 255 + 127.5 + 127.5 | 255 + 127.5 + 255 == 1530 damage.

If the damage was multiplicative, it'd modify the base damage instead, which gets accelerated by your chill bonus. Let's see the numbers...
1.5 * (255*1 + 255*1.5 + 255*2) == 1721 damage.

When I read this talent, I'd thought it was the latter. It was a nigh-pathetic talent that barely warranted a raised eyebrow. After trying it out and being horrified by the numbers in game, I ran the math... and my contempt only deepened. Tell me, how often do you hit all 3 waves of Blizzard? Pretty rare even with your team's help. Doing it by yourself is impossible, except for when barraging an enemy rooted by Ring of Frost. Ergo - you will derive 0 benefit from this talent for most of the game. On the off chance that you're lucky to hit two waves, that's a measly 127 bonus damage. Bro, you can achieve that with an auto attack if you were so desperate!

You will unironically deal more damage, consistently, with Numbing Blast[16]. If you initiate with Blizzard and follow up with a Cone for the root, you're guaranteed a second wave to hit. Had you picked Snowstorm, the enemy likely would have never been hit by the second wave in the first place. Funny, isn't it?

Well, say chief, what happens if you hit multiple waves and many heroes with it? Now you're getting a lot more damage in! Arguments I may hear you think. Practically speaking, if the stars align that such a scenario does occur, you can basically write off the fight as being won already. Any other Jaina build will have annihilated the enemy team by the time the third wave lands. Furthermore, if you were so inclined, you should pursue Northern Exposure[16] for more damage. Why bolster your Blizzard every 15 seconds, when you can deal +25% damage with EVERY ability, including Blizzard, NOT TO MENTION AMPLIFYING YOUR TEAM AS WELL!

Embrace the meme. Pick Snowstorm in Blizzard build for fun.


[Northern Exposure]
A terrifying talent to skyrocket yours and your teams' damage to the stratosphere. If your damage just isn't even up to snuff against big, beefy and tanky enemies, you will need this to fell the great beasts. Alternatively, if your team sports sufficient CC for you to land your entire combo consistently, then you'll love Northern Exposure.

With this talent, your combo will change a bit. You want to use your Cone earlier in your combo. If you have Ice Floes[7], always make sure to get that CDR boost through other means so you can reapply more -armor shredding.

Now, you may wonder, does the ability itself benefit from the armor shred? Unfortunately, no. The damage is applied before the armor shred. And since that debuff lasts for 2 seconds, and Ice Floes[7] can bring Cone cooldown to a minimum of 2 seconds, you cannot 'cheat' and boost your Cone's damage. Right?
WRONG. With the power of Icy Veins[13], you will recharge your Cone in one second instead. Now the subsequent Cones do +25% damage.
Also, your wingman Wintermute[20] will cast another Cone alongside you. Your Elemental's cast will always benefit from the armor shred!

So... why did I rate Northern Exposure[16] as yellow? Read the next talent.

[Numbing Blast]
Despite my praise of Northern Exposure[16], I pick Numbing Blast 90% of the time. Not only because a teamwide root effect is super handy, but because rooting an enemy increases your combo damage! Why? It's because of Blizzard! Now, you can reliably guarantee 2 waves to land on an enemy ON YOUR OWN, rather than a measly 1. Also, rooting an enemy guarantees every other ability to connect with target. Take it from me, I miss a LOT of abilities as Jaina! That's a lot of missed potential damage for no reason. Numbing Blast eliminates that inefficiency.

With Ice Floes[7] and Icy Veins[13] synergy, every E you cast against 2+ enemies reduces the cooldown to 1. You root people for 1 second. You can keep an entire team rooted for 5 crisp seconds. By the third cast they are definitely dead, but you can just keep going. Game winning talent if you can get a killer flank.

With the power of Wintermute[20], you may summon the Elemental a screen away, have him tag an enemy for the chill, and then mimic a Numbing Blast[16] empowered Cone. You'd be SHOCKED at just how many games I've won by catching an out of position enemy with this sequence for my team to follow up on.

Lastly, Numbing Blast[16] is vital against pesky, mobile assassins. If you can't hit your targets, you deal 0 damage. Stopping an overzealous Genji right in his tracks for a split second is enough to severely clip his healthbar. Not to mention your team can easily chain CC to secure a kill. I love picking Frost Armor[4] + Numbing Blast[16] -- if someone jumps me and get frosted, I can immediately root them!

---

[Cold Snap]
Interesting. Meaningless. The Snap that occurs in the center activates 6 whole seconds after the initial cast. Reminder: RoF comes out, it roots people for 3 seconds and then leaves behind the cold ring for another 3 seconds afterward. Only after that slowing ring expires does it re-fire. Who in gods name is still alive and of all places within the Ring? It's also as predictable as the morning sun. All it takes is someone to pay attention to your level 20.

The cooldown reduction on heroics is often times just not impactful in Level 20 teamfights. If you hit 1-3 people, you've just reduced RoF's CD at best to 25 seconds. The fight's going to be over before you recast it. Or, you hit 4-5 people instead. Well, if you land a RoF on the whole enemy team and your mates are with you, those guys DEAD and I think you've won the fight already. I've never seen a 5 man Cold Snap in my 9 years of playing HotS. Fun to think about, but the train of thought practically ends much sooner than that.

[Wintermute]
By the grace of god, in his infinite wisdom, Jaina has been bestowed the most busted level 20 in the game. Automatic pick in almost every match. Wintermute doubling every ability you throw out is a catastrophic amount of damage. Not only that, but sheer volume of abilities ensures that you will always be frostbiting your enemies. Finally, Wintermute goes a step beyond and mimic talent properties too. It'll also apply a root or armor shred off your level 16 talent, or Icelance[7]. There is a blacklist of talents that will not copy, as it'll turn Jaina mega-busted broken if so. Here's the list:
[*] Arcane Intellect[4], and Ice Floes[7], and Snowstorm[16].

The range increase is a nifty boost that helps every so often. It ensures that you can always plop down Elemental as a flanker or chaser. You'd be surprised how many games I won by casting Elemental > it attacks for Frostbiting > root an enemy from across a lane for my team.

[Ice Blink]
Getting caught in Leoric entombs? Do you need to get out of dodge seeing that ETC approach you? Is the Falstad about to blast you to smithereens? A quick and dirty short range blink for an immobile mage is a game changer. I'm certain this is the shortest range Bolt of the Storm in the game, but you get a nifty frostbite applicator in a rather large radius. If survivability is your top concern, you may need to pick this over extra damage or utility. You can't deal damage when dead.

I also love catching people off guard with my blink. If you need to kickstart the fight with a cheap chill, Ice Blink can blink you around to the side for maximum wide arc cones. Landing a Cone on 2 people will maximize Ice Floes[7] value, and in conjunction with Icy Veins[13] and Numbing Blast[16], you know the rest. This is also a great setup for an immediate Ring of Frost after, especially since Cold Snap is such a terrible competitor on this tier.

PRO TIP: The range of your Cone (7) is the same as the blink forward (4) + chill radius (3). For reference, you have a basic attack range of (5.5) -- if you're close enough to an enemy land your Cone, you are close enough to blink straight at them and have them chilled for your Cone!

[Deep Chill]
You do not know how horrific a 40% slow until you get affected by it. Doubling up your frostbites to cripple entire teams is very attractive. I love picking this against melee-heavy teams where shutting down their ability to move invalidates their existence. All slows do not stack. Instead, the strongest one is applied at a time. You should not pick Deep Chill if you've got heroes on your team capable of applying strong slows. Inversely, if your team completely lacks CC but have a plethora of damage, Deep Chill is incredible!
