Varied damage across the body

It would add an added layer of strategy to combat and add more skill than just point and click (although i love that style as well.) What I mean by this is, for example. If you hit someone in their chest, it should do extra damage than their leg. I also think each limb should have it's own armor bar based on what armor is on it, not just a total of all the armor on you. For example, if you are wearing a diamond pair of leggings and leather chestplate, the chest should recieve more damage as it makes sense that it's not protected enough. I'm not sure about how this would be implemented other than giving each limb a hitbox, but i feel each one should get it's own attribute. Maybe getting hit in the legs slows someone down or something. Imagine the strategy of this, as now you have to aim for specific parts to do specific damage, and inflict specific effects.
