I love my WHM, but i think it should have something that is more for itself... since they changed its protect and stoneskin was nerfed... it never had anything that made it special. besides is OP heals and regens
I think what WHM would need is a full life, auto life, AOE esuna, or another MP restore. As far as DPS skills, i think a AOE earth spell like Quake would be awesome.
