I am toxic (no joke)
I say mid or feed in champ select. If I die first blood then I leave my lane and go to whichever lane is winning. I steal farm from whoever starts to flame me first. If no one flames me, I afk. Funny thing is I only die first blood about 20% of the time so my winrate is still about 50% (thx rito matchmaking).
This is okay because I am a utilitarian. Since I enjoy trolling my team, 6 people are having an enjoyable experience (enemy team is happy for the free ranked LP) while only 4 are having less than normal fun in the game. If my teammates have a super negative experience in league then maybe they should go to a counselor. It's a game after all.
Been doing this for the last 2 years and have never been banned. All because I don't say kys in chat. Only reason I am posting this is cause I am getting married next week and am quitting this game.
