I play WoW since 2008, and loved to PvP especially during WotLK.
I'd prefer to play without CCs. I mean, less stressing, more fluent battles. I really hate CCs. Both to do and to receive.
I have always been an healer and really know how annoying is to cast when you are targeted by more enemies.
Every class can interrupt, every class can disable you in some ways.
It's a pain to cast, especially in bgs.
I thought I would have appreciated the CC nerfing in WoD but I didn't felt it honestly.
Don't flame me, it's just that I enjoy more the simple things. Only damage and healing, and it would be perfect to me.
