I use auto aim. I made this thread because there was an old thread about someone asking how to do this. I just was trying to help them out. you should try and act like a premium.
Alright, to all of you who say it makes a difference, set up some tests and prove it. I honestly haven't even tried it, so I'm not saying that you're wrong, but I'd like to see proof. As I mentioned in my first post, it could be in your heads, just like the "sub" level sensitivity myth. And guys, there's no need to flame each other over this. Arguing about it is just dumb until we see some evidence from either side.
Hell, I play with auto-aim, and the only time I ever notice it is in campaign. Matchmaking, and generally online multiplayer don't seem to be affected for me. I want to back up "it's all in your head" because the only time it drags you is when you are really close in campaign and you aren't aiming down the sight/scope. Maybe sensitivity has to do something with it, it's just like the sticky cursor in Halo Wars, if you provide enough 'force' to it whilst moving away, it stops being sticky.
