Although not perfect, I would love to see a new aspis like shield that would take up a gun slot in BL3. The idea being that yu can swap into it instead of a gun. It would have bullet reflection and element absortion and a throw mechanism. These things would also give massive melee bonuses. Red text effects could be taken directly off the Athena skill trees like shield regen, multiple throw targets, etc. The idea would be to encourage quick swapping between a gun and the shield in combat.
