It would be fun if you had some type of leadership/social perks/skills/abilities that would make you better equipped to handle dissension in the ranks and perhaps to influence npc's as well. A charmed merchant or employer could find it in his/her hearth to throw in some extra arrows in the deal or pay some extra for a mission well done.
I would also like to be able to turn this social interaction system off to experiment with impossible combinations of characters. Palladins with a priest of darkness, a priest of light together with a merry troll(or maybe all this social interactions just doesn't do it for me).
