I think that, at max, a two-round cooldown would be acceptable. 1v1 Fights last three or four rounds with one spent buffing, so that would leave the skill usable for 1v1, XvX, and PvE.

Hexers are supposed to be the debuff class, but they can tank, debuff, and deal respectable damage all at the same time. With one class. I would say that they should be nerfed in other places before their class identity.

Also @Lonestar, crit builds deserve drawbacks too. I say this as a Conduiz VA/Evoker.
