There's some decent ideas there.

This one would annoy the crap out of me, though

"For healing spells, casting single target heals with no target selected will automatically target the member of your party with the lowest HP."

If I don't have a target, I'm probably trying to heal myself to stay alive to then tend to the party. So the game deciding for me that that dps with just a little less health is more important would be pretty infuriating.
