You get a lot of those in competitive games anyway, DotA is no different. You need to have a lot of skill to be able to enjoy DotA, much less for LoL. I have been playing DotA on and off for 7 years now, and I can still find myself playing like a complete noob at times. The skill diference between the top DotA players and a player 500 games in is enormous. Edit: Oh, and because in DotA(2) the actions of one player in a 5 second time window can completely change the outcome of a game, 4 people gets frustrated for every mistake you make. This trait makes DotA(2) players one of the most short tempered and foul mouthed of all gaming communities. LoL more forgiving for mistakes made by one player, but because there are so many more noobs playing LoL the same outcome is achieved.
