The idea of being able to select ranged/melee attack priorities came to me last night. I'm not sure how feasible it would be to implement, but I thought it would be interesting. :)
Instead of the fixed DD -> Weapon -> UC order, you could choose the priority for ranged and melee combat.
In essence all this would really do would be to allow a minion to cast FB/MM in ranged and then use a weapon in melee, but who wouldn't want a Ryu/Ken UC character able to through a few Fireballs before finishing with UC in melee. :)
