Matchmaking still proves favoritism in algorithm

Still being forced into matchups that blatantly place me against setups perfectly put together to destroy me. Proof? I get 5-7 in a row; switch setups, & dont see another setup AGAIN like the first 5-7... UNTIL I SWITCH BACK!!! Then, the same setup types that beat me the first 5-7, I start facing AGAIN... Blatant match-fixing! Random = ?
