I despise aim assist. I usually just turn it off because in my opinion is that its flawed in that it at times does the job for you way to much. Just like someone mentioned Aim assist can greatly interfere if you want a sharp and precise shot with your sniper rifle. I also want them to limit aim assist greatly since in MW2 it help a bit to much especially for those new to the game. Your suppose to learn how to aim not let the game do it for you. I might also want to add that the lunging for the knife needs to go back to how it was prior to MW2 in that it took a certain amount of skill and precision to pull it off. Theres alot to point out but I pointed a few problems that I want to see improved in the next call of duty title.
If Im not mistaken aim assist didnt apply to Hardcore before MW2 that is. If Im wrong then Im wrong (never really used aim assist for the most part)
Most people seem to be taking about the Aim Assist, but the point I most agree with is the teammate spawning. I noticed the exact same thing as you in WaW. I would be flanking around with a silenced weapon, and then 5 idiots spawn next to me shooting off bazookas and LMGs, getting themselves raped and me in the process. Very annoying. I would really appreciate a more "tactical" approach to spawning in this game.
And on the flip side: I am flanking a sniper who I saw pick off one of my teammates, and JUST when I've finished teabagging him and am going to shoot him in the head with my magnum, 3 of his teammates spawn around the corner and ambush me. This is what can happen with this type of spawning.
I vote for something new.
