Bad matchmaking

I keep getting trash matchmaking and it costed me a lot of my ranks. I went from nearly masters to plat 4. That’s a colossal fall. I am not sure what to do anymore because my matchmaking quality is still horrid . Please fix my matchmaking. I am sick of awful randoms and I need my rank back for tournaments.

agreed, me too, its been happening a lot recently, it was fine before but now im losing almost all my games
