Please roll back the matchmaking system

I'm sick of playing unwinnable games where I go 30/10 and delay the game past 60 minutes by myself The games are way too lopsided... like, I just played a game where it was like [4 Silver, 1 Bronze] against [3 Bronze, 2 Silver]... Like, why are these teams so one sided???? Why???

I just want to play some fair games for once... things are either too easy or impossible... where's the middle ground???
