I'm all for 4 weapon slots. Or, as I suggested before. Let us put weapons where ever we want to. Any weapon in the Power ammo slot (tier 3, heavy ammo) will have a greatly increased buff when using power ammo. This way, we don't have to fight over power ammo or wait around for it. We can just play and if we come across the power ammo. We can pick it up and one shot someone with a handcannon.
