Just like KZ2 situation. " Oh god , it is so bad , I can't even play , make the controls like COD4!!!!! " . No. You are the bad one , if you can't play that's your problem. You gonna get used to it or quit playing it.
I don't think standardizing controls on FPS games would be a bad idea. There's no good reason why every time I switch from KZ2 to R2 to $FPS_GAME I need to get used to different controls to do the same things.
