It's 2017, why do we still not have a way to flag unskilled players in ranked?
This should have been added long ago, and is necessary to fix how fucked up ranked is right now.
i.e. just played with a one-trick Quinn who rushed Ghostblade against Cho'gath while already behind, then started intentionally feeding because they had no kills and didn't want to play the game unless they were fed, but we wouldn't surrender.
This is a textbook example of players who don't belong at their ratings, but one tricking uncommon champions and the state of the game allows them to maintain.
