Why is Matchmaking so terrible
No Riot, pairing an unranked player with Gold and some silver in between and a plat player is not good matchmaking. It's terrible.
2 silvers and a plat player doesn't equal full high gold opponents.
Two oranges doesn't equal three pears.
You can't sprinkle in a plat player with an unranked team and expect a decent game and not a clown fiesta. I haven't played a single match that such teams made for a good game and not a rage inducing fest.
