Right now there's actually no reason to have points in dual wield and points in ranged. Instead, put those points into warfare. As an added benefit, it allows your melee weapon wielders to use knockdown CC skills like battle stomp. 2h fighter with poly is better in general than 1h fighter and you don't need to put points into constitution at all just stack physical armor with someone in the group who can cast armor of frost on you. Putting thievery on your undead character makes sense because they don't need lockpicks. Whoever has pet pal should be your persuasion guy and in general, this should be your summoner because summonings don't use intelligence so you can spread your attribute points and win persuasion checks more easily because of it.
