Ever have those parties that shouldn't work out, but end up okay? The ones with a Lawful Good Paladin and Chaotic Evil Rogue. The ones with a Pyromancer Sorcerer and a preserve nature Druid. The ones where somehow the problems of each character make them work together better than ones that are supposed to be more unified. I've had one or two in my time playing and DMing.
