So, someone was trolling in champ select and even admitted he planned on feeding in the game. I leave it up to your imagination to find out who it was.
So, it's either -20 LP or so or -3 LP for dodge. In any case, I, as a player, get a penalty for doing absolutely nothing wrong (PS. I dodged).
I would send Riot a support ticket but none of the accounts I've reported so far got banned. After the report, even scripted bots are still farming IP and levels up to this day in AI games.
So, ty Riot, ty community. All the more reason not to spend any $ on this game.
