Holy crap if you take advantage of this, you will have 1-2 seconds advantage over someone else if you are behind cover.
Basicly you will be able to shoot them before they see you because the animation they see of you going from prone to stand is longer, than you going from prone to stand in your screen.
Everything in this game has a 1-2 second delay. You think you are around the corner, then die.
I tried this in a private match. The animation plus the lag makes this way to broken.
this has already been proven in the few videos/threads that's been posted. obvious game flaw.
