Ascendants in plat lobby???

Please fix your rank system... i literally got 3 ascendants and 2 diamonds in an all plat lobby. Though their ranks are diamond 1 and plat 2, they had ascendant gun buddies. I also lost a lot of RR despite being matched up with people 2 ranks ahead of me. If this continues then the game is pointless. People from high ranks can just clap you and you will keep losing your games.
