Hitting different body parts

What I mean is different body parts do different damage like if you get hit in the head by an arrow and you are not wearing a helmet you can die instantly but if you get hit in the leg you can't run for 3 minutes and stuff but also this can be really good for combat this can make a good skill Gap between bad players and good players also there can be different takedown animations what I mean is that you can grab your opponent's leg if you aim at them and then an animation where you grabbed there legs and pull them and they fall on the ground but they can get up fast but you can use that time to hit them but yeah tell me what you think
