You know a system is broken when 50% of the games this season have a plat and bronze player in the same game. Add to that that I have literally had an unranked player playing one of their first 10 games on my team 8 of my last 10 games, and you get an unplayable game.
First of all, this matchmaking needs to be fixed. There should never be a plat and unranked in the same game. There should never be a gold in an unranked in the same game.
These unranked players are all worse than most bronze players and are plaguing ranked right now. Whoever decided they should be starting in high silver/ low gold elo is an absolute moron and shouldn't be employed.
