Matchmaking at its finest

http://imgur.com/RquSIoM I was playing a match as Nidalee jungle earlier today and ended up fighting 3 platinum players..... Problem is that my team only had 1 level 30 character, and their team didn't have levels like 1-10. Pretty sure this isn't meant to happen.... (Yes, I am smurfing to get to level 30 again. This was an old account that I wenty from level 1-23 to learn again, but decided to come back to it and get it level 30)
