Ok Caleb Zart, since the game likes to imitate reality because we still don't have the movement of rolling while lying down that would help to erase a Molotov received in the body, overcome barriers in stealth mode or be able to dodge shots if snipers from a distance?
Imitating reality isn't the same as being constrained by it. Just because something is real doesn't mean it's fun. That has to be kept in mind always! Many of these things are specific design choices to support the gameplay in the best way possible.
