Hell, by Swen's stated goals of making it to where the MP doesn't have anything in it that the SP can't have this makes the most sense, since the AI won't fight you on anything you can't have any competitive questing unless you are able to fully control and roleplay more than one character.
I do not want to be forced to roleplay more than one character against each other. It's pointless.
Also, Competitive questing and the DM/GM mode already goes against that stated goal, so that pledge is already broken.
