SCH deserves somewhat of a makeover since neither Summon Seraph or Seraphism really thematically fit the class... Let the Job have its fairies, no need to try to turn it into an angel themed healer for literally no reason.

As for WHM, I think what that job needs is more relation to their Conjurer roots, they're just the Light Mage now instead of using any of the elements. I think Aquaveil is the only thing that's not light themed at this point.
