It actually took me a little bit to think of this one really.
Afflatus Misery has a ton of potential in dungeons and could be quite tasty if we get a chunky add phase in one of the new raids or trials.
The rest of the WHM kit feels fairly subtle by comparison really. SCH will be quite the healing powerhouse and there's every chance I may even end up having to play it next tier. Not my preferred healer but the new kit will suit my play style. I'm still a bit apprehensive about AST.
