People Afk for one, and only one reason only. They think that if they have 2000-3000 hours, they're pros. Here's where you go wrong. Pro stands for Professional ( in case you didn't know ) and becoming that is long long long way. You only become better by playing the game. Hours or stats don't effect that mutch.
Imagine the akward moment where you have 3000 hours and player with 200 hours Knows alot more than you of the game. Play the game! That's what it's made for!
