I really love this game and am always thinking of ways to make it better. After long consideration I thought up basically this system to balance and make things a bit more in depth. Essentially you have a chance to lose a limb if you take 3 hearts in a single attack (Bombs, Power Attacks). Losing an arm means you wouldn't be able to use shield mechanics or attack while holding all things. Loss of a leg would mean you can't move very quickly or swim, still having two arms would mean you could use your shield as a crutch. Of course archers and builders wouldn't be affected by this. Alternatively you could cut this out with an armor health system. After taking a large amount of damage a knights armor breaks and they take extra damage. The overall goal of this mechanic would be to prevent camping and stuff like that.
