Sure, it takes a little more practice to use than MW2's simplistic controls, but the rewards are immeasurable in terms of flexibility and realism, not to mention accuracy which _is_ measurably greater.
Of course, I wrote countless posts on the topic of the joystick control when MW2 first came out, as others did as well. The response from Tim and the other Activision posters at the time were almost identical to the posts we see today in response to criticisms of Mercs' futile salvage system and forced-retirement. They're "sorry to hear that it's frustrating people", and they're "looking at changing it".
Well, apparently last year they weren't sorry enough, and never got much farther than the looking, because the forced-centering is no less forced now, a year and two games later.
