Flex rank needs to be tethered to Solo/Duo rank
As a silver 1 player in flex, I'm tired of seeing a player on the enemy team be bronze 4 in flex, but plat 2 with a 54% win rate in solo queue, and the matchmaker treats the person as if he's bronze 4. The ranks really should be tethered so that they can't differ by more than 4 divisions no matter what.
