Ragers are not the downfall of LoL. Feeders are not the downfall of LoL. Morons getting caught 5 times late game and blaming it on the team is the downfall of LoL.
I do not believe in the "carry yourself" nonsense, as long as these narrow-minded people that can't understand a basic fact exist. Besides, would it be normal for a guy who plays like this to raise in elo?
