If this is some kind of weird troll post, well done steak, you made me laugh. If you're serious, still well done marshmallow.
I think that this is by far the weirdest post I've read this week. How does an onscreen gun, which moves by your aim, affect you in any way due to you being lefthanded? If they were lefthanded, the controls would still be the same cause the gun is in the middle and not towards a certain side.
I'm assuming you use this same argument when playing other FPS' whenever you're not good?
