Turning off animations - right now, about half (if not more) of the time I spend in missions is waiting for the animations to finish playing. It's no big deal if there's, say, 7-10 units, but if there's over 20 active units, it's a bit much.
EDIT: An AI setting that makes the character stay away from enemies as much as possible. I once had an AI Psy Healer attempt to backstab me, who probably realized he can't attack.
