Hi! I've just met a player in a ranked lobby that was autofilled in support, and he decided to play syndra, while saying us we would go mid, i put some screenshots.
If any Riot employee see this, consider putting a report system in the ranked lobby, because he's probably doing this every single time he gets autofilled and no-one is gonna stop him because WE CAN'T report him unless we play the game with a troll.
If you have the bad luck to meet him in a game where he is autofilled, dodge him because he probably is going to troll you...
