It seems like a missed opportunity. Why can't you fight against your team mates in a solo run? Its more work for the devs, but it seems like something that should be on the eventual to-do list.
Also, dominated player characters should have some sort of limit on how many consumable items they can use per turn. Its pretty frustrating to watch your dominated glass cannon char chug 4 pots in a row, use 2 scrolls to buff the enemy, then use adrenaline, chug another pot AND a source orb. Not even kidding. It made me die a little inside watching that.
