[2021] Golds on Diamond Lobbies

The new MMR system is rigged, I get why its added to the game but today in my diamond lobby I had an unranked jungler in my team, and I had a silver in my team as well, the silver had a total of 5 games with 80% winrate, is that really all it takes to join diamond lobbies.

Make a new account play 5 games win 4/5 and join high elo lobbies.

After getting at least 1 or 2 golds in my team every game, I dropped from diamond 3 to emerald 2 because some lucky golds won some games and joined lobbies they can't compete in.

Game is unplayable and Frustrating. I would hope they fix this and make it so they have to play more games before putting them in high elo lobbies.
