Matchmaking?

I complained a few months ago because I was only getting placed against diamonds and plats. (im gold elo)

Now i'm only getting placed against bronze.. Wtf is happening (still gold elo)

My win rate is still pretty high, (around 54% i think)

and solo mmr is around gold 3 ish. I don't mind silvers or low plats, but I dont want to fight bronze or diamonds.. just let me practice against similar skilled opponents so I can improve lol
