First off, please done post unless you can use proper english/grammer. At least so we can understand what you are saying. Second, I have 35 days played on MW2 and I have no problem with the aiming in this game. If you didn't rely so much on the aim assist in COD, you wouldn't be having this problem in this game. Aiming actually takes more skill in this game than in the COD series. All you have to do is get used to it.
first of not all people are english and now how to write it good, so keep that comment for yourself are stay out of the forum.
atleast hes not using sms writing and he is probable doing hes best to make no mistakes. like me
ontopic: aimassist is horrible in any game, try to play without it for few weeks and you will see you getting better in killing the enemy
