Yeah, I was 37 around Gleeba. I've noticed since getting my full party together that XP is considerably slower.
What I'm finding slightly aggravating is that putting your characters on auto gives them a significant advantage over your personal control. If someone gets hit randomly but I've already instructed my Priest to do something other than heal, too bad until the full next turn.
However, if my Priest is set to auto (Focus on Healing) and it hasn't been her turn yet, she will heal someone even if they were full health until a single turn before her turn came around. Basically on auto it seems my characters can change strategy on the fly mid-turn and I cannot. So there's basically no advantage to manually controlling and a pretty stiff penalty for doing so.
