My only gripe with this game is that you can often lose fights on higher difficulties just because of bad ally AI. This was a problem in Persona 3 and the same flaws show here. I would prefer control of all party members, but if that is not possible maybe allow players to target specific enemies for attack or specific allies for healing and/or buffs.
