That's not what got you banned; it was your treatment of the other players. The tribunal, and Riot, don't care how good or bad you do. They don't care if you were a godly 50-0-20 carry that won the game in 15 minutes. They only care how you treat your fellow players. Since there was enough of that in your history to warrant a ban, when Riot -manually- reviewed your case after the tribunal -recommended- punishment, a ban is what you have. It's also not ONLY the games listed in your card, but your ENTIRE history.
