Ranked Duo system.

There should be an option to opt out of playing solo queue with or against duo players, or to at least decrease the range at which people can duo from an entire league to a few divisions. Duos will either end up carrying the game cuz one is plat 1 palying against plat 5's or vice versa where the lower level duo who would be gold 5 will end up making many mistakes and making it difficult to play or even enjoy that game.
