I think it's kinda funny and weird that you can lean while prone. Try it in real life and compare to how far you can do it in the game. Plus, firing a rifle accurately while leaning in the prone position would simply be out of the question. I hate to admit it, but I was leaning while prone and sniping people like crazy earlier today. All they could see was my head poking out and I had the full accuracy of prone position. This should be fixed!
