After digging into skill fruits a little I noticed that Ice is retardedly overpowered. Most basic attacks for each element (30~40 power, 2-4 second cooldown) launch a single projectile. Ice missile lobs three, and they have a chance to freeze (+ guaranteed slow) so that's 90 cumulative power on a 3 second cooldown. If you've played blind you might recall that the Peking dungeon was notoriously more difficult than basically anything else you could have encountered up to that point because of the 4-5 Pengullets spamming Ice Missile. This is why. In comparison, a similar skill for Fire, flare arrow, has 55 power and a 10 second cooldown.
The broken doesn't end there. Ice's ultimate skill, Glacial Spike, might be a little short on power (130) compared to other nukes (150), but it leaves behind a widespread damaging icy mist which deals full impact damage per tick. It's incredibly hard to dodge yourself and guaranteed to butcher your Pal unless you recall it. That's why your stuff randomly dies while fighting Lyleen Noct.
The remaining attacks might not be as good (Icicle Cutter is actually pretty underwhelming despite piercing) but Ice Missile and Glaclai Spike actually give you fantastic coverage even versus fire/ice types because of their raw power. Even with the damage halved IM is still more powerful than other spammables. The best compliment for those would probably be either Seed Mine (even though you'd technically be gutted vs Fire) on account of its sheer nuke potential or Acid Rain due to it being a homing and having 2 sources of DoT.
