I'm very much looking forward to the changes in WoD actually.
Currently in 2s nobody (besides priests) ever goes oom until dampening reaches a very high percentage. In threes, it's a CC then huge HP burst down, peel and healer has a huge HP burst up, burst down cycle.
People will still have plenty of tools for PvE. wow gold fr Yeah, perhaps you'll have to consider what button you're pushing instead of just hitting whatever you feel like all willy nilly as there's currently very few ramifications for poor gameplay. I've healed every single expansion this game has and never has healing felt so unrewarding.
So yeah, bring the changes on. I can't wait for WoD to drop; every indicator says it's a step in the right direction to me.
