Well, I got permanently banned.
Let me start this off by saying I am not expecting to get unbanned by posting this. I know the consequences for my actions and am fine with the punishment.
Nothing much to say to justify my behavior. Got too tilted, said a bunch of bad stuff I shouldn't have, didn't take a deep breath, pretty much sabotaged my team, flamed both the enemy and my own team nearly the entire time. All in all I was acting in the exact manner that gives this game and the community a real negative reputation.
Let me serve as a warning to others to not be as bad as I am. If you are doing not too well in a game, don't do what I did and behave like an asshole. Inhale, exhale, take a drink, do whatever you take.
I paid the price for my asshole behavior (90 dollars in cosmetics and champions if I recall right) and now I get to think about my actions. To the people I insulted, it ain't worth much, but I am sorry. I really needed to chill and get good.
