I always hated the way that you had a real disadvantage when peeking round trees and houses on the wrong side, think its a right corner. As you have to expose more of your body than when you look around a left corner. So if you could switch to your left hand and essentially fire round a corner without exposing all of your body, that would be great. Only allow it on certain guns, not some Bullpups (not P90 or FN2000) or weapons that dont have an effective brass deflector. Maybe putting somet like this in the config
I dont think there should be any penalty for using one hand over another as most people can shoot just as well left handed as they can right handed. It would suit llefties in real life more too, like counter-strike did, oops forgot it was an offence to mention that game.
And no I am not left handed.
