Going back to the trinket Lifeblooms mentioned earlier. I can only speculate that a nerf for it is inevitable, seeing as how it wrecks the healingmeters. Same for keeping your Lifebloom rolling when you have the Carrion Swarm on Anetheron. It's just a matter of time really.
Looking at the sheer amount of raw healing a Druid can do on Hyjal trash for example seems to me as insane. I guess it should be classified as being overpowered.
