As long as SE tries to keep each healers personality in tact we should be okay. I'll admit ASTs and SCHs identities are a bit meh right now, AST more than SCH, but WHM feels like it should, the healer equivalent of BLM. Powerful heals and powerful nukes every so often, and minor raid utility. Granted, I'm not too sure how to perceive Temperance, but I I've heard good things, mostly.
