Even now it's taken just skirting near the idea of tank/dps balancing being looked at and it's all people wanna focus on. Healers have been unhappy for a lot longer than just this week of the media tour. Years in fact! Why else would so many of them collectively respond so negatively to the prospect of using their kits again like this for another 2 + years!?
For what it's worth I think all mits on jobs outside of healers should be limited to use on yourself only. Primarily this is for DPS mits really. That way you can press them, help your healer and not upstage their role and also it's a good indicator of which players are refusing to cooperate and use the mits because -they- will be the ones who died.
