Flex ranked mmr system is completely broken, what is being done about it?

I'm going to have to quit this game if flex isn't fixed soon. It's so miserable to play vs people that are clearly 900x better than everyone on my team, and waste 20 minutes playing a game that was decided from the start. There is no resemblance of a working mmr system. There can be a bronze person in the same game as a diamond person, like wtf is that? What is this 4 golds and a silver vs 3 plats and 2 golds? That is not balanced at all.
