Only 4? That's still pretty low.
You might want to keep trying to adjust to higher sensitivities. At least an 8. (I play on 12 myself)
Anyways, imo I think having good aim depends on the controller you have.
I know many people say xbox controllers are made for fps, but that's a load of bull. They only say that because of their "gunlike triggers". That means nothing as their analog sticks are crap.
They're way too stiff and it's hard to aim precisely with them. The PS3 analog sticks are softer and it's wayyyy easier to make small and precise movements which leads to better aiming.
There's also the matter of having a tv with a high response time.
Aiming is loads easier on a tube tv than on an lcd/led. I have not tried a plasma, but I hear they're also fast, so if you have one of those, I think you're good on response time.
Of course this is all imo. Good luck on improving your aim.
Do realize most professional Call of Duty players play on a 4 or 5 sensitivity. Of course, they play against other professionals and play objective based game modes which makes it easier to "predict" where the other team is going to come from.
Another reason (I think, don't quote me on this) they play on such low sensitivities is that it allows them to take long range shots and miss less in general. When everyone has incredible aim, missing one or two shots can be fatal.
Aside from that, improving your aim is just a matter of practice.
Professional meaning they get paid for what they do, and that title is in no way relevant to their actual skill level correct? There are loads of higher skilled people that aren't "Professionals".
But yea, you have a point~ I haven't seen much professional gameplay, but they do seem to play veryyyyy defensively, and they might not need high sensitivities while camping at the end of the map, but that's very boring gameplay imo.
Higher sensitivity was only a suggestion. It is a fast paced arcade shooter after all.
It makes the game more fun and frantic when you're moving around like a lunatic.
Again. All in my opinion.
The secret- the right amount of beer
Well, it's the "twitch" reaction that makes you a little less controlled. The anticipation and movement holding the sight over a moving target while trying not to get shot...
Try switching over to an AR and keep a long distance, therre you can pratice on "smaller" targets while removing the impending sense of doom you get while right up in someone's face.
It will transfer given enough time
