None of them seem worth picking over what we already had, just gimmicks. I’m actually missing Eye of Leotheras which they pruned since it was fun to use against casters.
Edit: I just read that chaotic imprint buffs your own chaos damage every time? That might make it worthwhile.
I feel like almost everyone is like a sheep and instead of trying new builds/conduits/talents to find it out ,they will rather complain or hate everything and follow only what icyveins/wowhead post and to answer your question ,yes we do use new PvP talents but it pretty much depends on whats your team and enemy.
