Next season match making

I really hope riot fixes this bullshit match making in rank. I just did promos and had 2 Unranked on my team while 4 golds on the enemy team. I'm S3, so why am I vs 4 golds with 2 unranked on my team??? Silver and Bronze holds more than 50% of the player base so Why are Golds in S3/S2 promos and Unranked players?
