They made the point pretty clear in the ViDoc. [url=http://www.youtube.com/watch?v=Ujln3hGw-E0]At the 2 minute mark if the video doesn't work.[/url] In short the input devices used are not equal. Controllers have constant input so it can deal with heavier recoil, whereas PC doesn't and so can't. Ultimately it's about game feel that they are aiming for. Disagree and all of that see if it gets you anywhere. Though from what I can tell things are largely not going to change no matter what you do. Not sure how flinch applies, because they never specifically spoke of it, however there's plenty on PC. Hell I have noticed that there's an inherent RNG factor to your shots when getting hit. So basically even if your sight is on target the bullet won't go there. It's pretty frustrating because a game shouldn't communicate one thing and then do the other.
