Since we're going in circles I'll just leave it at this:

SCH is really the OP healer. Even now.

When AST is buffed, WHM clear rate will go down, and Scholars will hold the pole position yet again. Even without any buffs. If SCH is buffed on top of that, it will really go into orbit.

WHM looks strong next to a weak AST. As soon as that's fixed, people are going to remember WHM still has no raid utility among other flaws. (But, hopefully, WHM will keep high personal DPS as its niche thing).
