I hate those people too... Although not every elite player is like that. I remember I used to be a friend and play together with one of the best of a certain shooter game a few years back, and he never once looked down at any less skilled players. He always did what he could to help them. (it was a co-op game where sometimes the better players would just let the noobs die and play on with the more skilled)
