Luke smith probably after he made an ice mage build in WoW and thought it would be awesome in a first person shooter.

I actually laugh it was a much asked for class (many referred to wanting a cryo class) during D1 and early D2, now that we have it many players are failing to adapt and counter it so they want it gone. I don't use stasis for pvp as it's too slow imo so I go against it often with the light based classes and you know what? I do fine against it. Sure on occasion I'll get frozen but it's either my own bad play to blame or those players popping their supers which usually ends the same way if it was a light based super anyway. Ive actually grown a fondness of going against stasis players as they tend to have a false sense of security esp the revenants, I run a chaos reach build and while the nades and melee are not the best the super is an instant break out and win move. The only difference is before stasis I'd use my super aggresively, with stasis I just use it defensively so a simple tactic change has kept that class and build quite viable. Daresay code of the missile titans are the same, and I've been running golden gun for hunter, titan and hunter I don't play much but still manage to counter stasis often enough
