The thing is you can still dominate and reach extreme levels of skill and competition on an xbox, PC gamers will never understand this until they do it themselves.
You'll never know what you're capable of if you sit down at an auto aiming console with sub par controls.You will find this out exactly using mouse and keyboard.
Rough count in my head, I got banned from more than 150 counterstrike servers for cheating... sometimes it would be my score, sometimes it would be the uneven playing field, 95% of the time it would be accusations of aimbotting. I have some friends who dominate on console, but they really can't pull off the shit I did in CS, not a chance.
Let me elaborate,
I played CS for 8 years, several of those years I was involved in every league there was. During that time I had 0.13-0.15 sec reflex, I'd whip my mouse and end up on your head, no readjustment needed.
Used a 300~ dollar pair of Sennheisers and got to the point where I could predict
exactly where you were and where you're heading using only sound. Learned over the years to take advantage of this in every map, dink dink, dead again through the wall.
Was able to control the recoil of the AK from the top of A in dust 2 to a smaller circle no bigger than the head of the team coming through cat. Learned all tactical advantages the league maps had to offer by watching the top matches/cpl demos religiously, a lot of those advantages required the dexterity of mouse/kb.
So I'm going to go ahead and correct your statement that console players do not, never have, and never will compare to the level of skill achievable on PC "until they do it themselves".
