"it's just a game"
I get it, it's a game. Obviously don't lose your mind and flame and shoot yourself. But this pertains to ranked. Again the former applies. But if you que and don't even bother trying. Like an adc that took adc from my duo and did less damage than the support. The enemy soraka support. Then you have the audacity to give us the "It's just a game why try" Yeah why try. Why do anything? Why wake up, why bother existing hell why do you even wipe yourself after you use the restroom? Playing ranked we're trying to win and have fun while we do so. I don't want to lane with you already my fun is gone, but I'll still try to win. Even when you don't lane or even play the game. Why did you even do it in ranked? Why not just go play a normal you care enough to play a ranked game.
tl:dr "it's just a game" doesn't excuse you throwing on purpose and honestly you should be banned from all ranked games.
