It would be an interesting feature if you have a two handed weapon and lose an arm if you could drop it and use your fist to attack or perhaps pick up a weapon from the battle to use from a severed limb from your team or perhaps your opponents severed limb. This would come in handy also if you lost a shield and chose to drop your weapon to pick up the shield or vise versa.
