Matchmaking System

I'm sure many people have complained about the matchmaking system, and I'm sure Riot's working on making it better. Nonetheless, I've recently run into a very upsetting problem that I couldn't let go without being talked about. Myself and 4 others just played a game of Definitely Not Dominion together, and we were paired against a team that was completely consistent of currently or previously Challenger, Platinum, and Gold players. We are all Bronze and unranked. I will not be vulgar in this post, but there's something very wrong with that, in my opinion. That was the least fun, most unfair game that I have ever played, and I sincerely hope at least one Rioter is able to see this post. Thank you for your time.
