Yea but Sch dps is still superior to Ast dps by a pretty decent margin. Sch have a reliable group dps buff compare to Ast which is rng. So if you pair Ast with WHM, don't you miss out on the consistent buff compare to having a whm+Sch. But if you go sch+Ast, you have the consistent dps buff of the Sch + the bonus of the nieces albeit rng buff of the Ast.
