My characters didn't level up at the same time. As far as I can tell, XP in combat goes to the character that gets in the killing blow. That's a little annoying in fights where you have NPC allies, because your party could potentially not get any XP at all.
Yes, if that is true, I think the penalty is a bit too steep. While I'm open to the idea in general for rewarding XP based on individual efforts, it may have to be more nuanced than giving XP only to the lucky one getting the killing blow. Perhaps rewarding XP based on percentage of health taken down on the kill by each character, although that still penalizes any build that is not purely offensively based (e.g., a melee character decked out with defense to be a shield for the party).
