Well we'll just make it so that when ironsights isn't on then the aim will be off..
How many people can hit a target far away holding a gun down at their waist?
realism is good but make sure to have ironsights come up quick.. that way people will still like the game...
also it'd be cool if hitting someone in the hands and arms would completely throw off their aim
but i don't think it'll be fun if their aim is off for the rest of the round (if we have rounds). maybe just for a few seconds..
