still not as bad as the league of legends players.
buts its a moba. either get used to the douche bagness or dont play mobas.
it doesnt get better.
also the MMR you get to in dota 2 when you first get yours is not even close to where you actually belong. they do not give you enough games to see. youll either move up or down quite a bit over the next 25 games.
that said my steam name is tunaburn and i play dota 2 pretty much every day.
