As much as I would enjoy it, I still feel like strong Self Heals are a WAR thing. Clemency is a bit different as it can be used to help the party (or atleast I'm sure that's the given intent) while still healing the PLD.

Maybe I'm wrong, but I'd be more interested in putting up a Galvanize effect on ourselves instead. Maybe as shroud's of darkness that get built up every time Dark Arts is used?
