Matchmaking
choeatsporo - Summoner search results - League of Legends
On my team: three less than level thirty, and one unranked player. On the other team: Two diamonds, a platinum, gold, and unranked.
I mean, I know the MMR in normals is separate from ranked play, but regardless that is a massive jump in skill level and rank. I am posting this only because this has not been a random occurrence. I can't name specific instances but a large amount of my games, in normals, seem unevenly matched.
