I always thought that if the game implemented a unarmed combat but as in if a guy drew his sword and ran at you, you may disarm him and either use his blade against him or finish him in some way.(A stomp to the head would be sufficient no matter the armor) Obviously on the other hand, punching a set of steel armor is impractical but this would make it so it's possible to use a character without a weapon in hands at all times and come now. It's badass to walk into a place and not have to draw your weapon to clear out a group of bandits.
