[QUOTE=Hyrage;287586]I don’t get it. Is it that hard to believe that some gamers are actually more comfortable with a controller than a mouse or that some others came from PC and actually prefered the feel of the controller for the overall experience (especially the progressive character movement) and now are skillful with such accessory?
It doesn’t sound inhuman to me.[/QUOTE]
I think it’s hard to understand, rather than hard to believe
Controllers are simply not capable of providing the same accuracy and speed as the mouse and keyboard, even with acceleration applied to the stick inputs. I can totally understand that you feel more comfortable with a controller in your hand, but unless you’re genuinely a lot better than most mouse/keyboard players, you’re going to be at a constant disadvantage.
I can certainly see why controllers for PC would help disabled players as someone mentioned earlier on, but again - if they’re playing against mouse/keyboard-equipped opponents, they’ll need to be better than those opponents to avoid constantly being slaughtered due to their controller choice. Being beaten due to being out-skilled is one thing, being beaten because you’re wading through quicksand out in the open rather than darting through the shadows of the arena, is a whole different kettle of fish 
Most console FPS games reflect this disparity - damage to the player is lower, survivability is higher, and it needs to be - because the controls are slow and ponderous, or twitchy and inaccurate - there’s little chance of hitting middle-ground, even with “clever” acceleration. Hardware aside, controlling a small stick with your thumb also can’t compare to using your entire arm, half of it, or even just your wrist with a mouse - whatever your style, approach and sensitivity choice with mouse control, it’ll beat analogue sticks every time in an FPS. Mostly you’ll be passing someone close-quarters and shooting them in the back, as they slowly try to turn around to face you - or spin wildly due to high-sensitivity optimistic settings causing their fire to go in every direction but towards you
