I can't fathom how much I'd have to play to be able to have those reflexes and to have my fingers fly over the keyboard. I was thinking that they have gaming mice/keyboards but that can't be everything.
It's not envy from me, but I'm just a casual player looking for some fun and a shithead decides to ruin it all by killing me/other players once every 10 seconds. But in some cases the others unite and leave the server and the guy alone. Who are you going to annoy now?
