ya COD has auto-aim up to the eye-balls. When i started playing COD 5 online, i would pick the bolt-action rifle, thinking realistically it would be the most effective, but while you aim people carefully people just strafe with machine guns, hold the trigger and let the game do all the work (you can clearly see it in the kill-cam). It's really dumb.
COD hardcore playlists are good though (too bad you have to play for ages to unlock it and it still has the stupid dogs- like, imagine if in halo, when you got a killing frenzy you would get a swarm of buggers- that instant kill you- to help you for about a minute, people would go insane, yet they have that -blam!- in COD and it's acceptable. ridiculous.)
