Uneven matchmaking

So for my first game with this new champ select the matchmaking was very uneven. I'm not good at this game and don't play ranked much yet sub how the enemy team had 3 sub level 30's and my team myself and one other person had over 500 unranked wins and we where all over level 30. Here's a link this match went pretty much how you would expect.
