No beating around the bush today. There were some upcoming healer changes that were announced earlier in the week. I can tell you as of right now, I'm worried about the Power Word: Shield change -- not because I think discipline priests will remain overpowered, but because holy might go the route. I'll explain that later on in the post.
The main focus of today's post is defensive cooldowns for shaman and druids. I'm sure a number of players don't believe there's a need for the two classes to get defensive cooldowns, but in order to compete for utility, I think druids and shaman would benefit greatly from having those spells available. The argument here is that since the four healers are approximately the same across the board (from a throughput perspective), the edge might be given to paladins and priests because of the additional cooldowns they have to offer. Shaman and druids might end up being even more attractive in 10-player raids.
