When i read this news from ptr patch notes i've passed away :P
WoG put on 20 sec cooldown, and the mastery of holy remove the CD (not clear if still gives old bonus), mean that for a protection paladin autohealing is not more possible or at least is reduced a lot.
I've seen only nerf for us in this patch note (mana for heals is not a nerf, but only a return to old state before 4.0.6). Why blizzard hates us so much???
