Matchmaking is broken.

Ever since preseason started, almost every draft pick game I played I was matched up against Diamond players. I'm at most low Platinum and the People I usually play with are Gold at best, so why tf do we almost exclusively get matched with players waaaay above our skill level? Friends of mine that can't get out of silver have found themselves facing a damm Master player. The few Matches we don't get destroyed in, it's the other way around: we get silver Enemies at best and tear them a new one. Neither is fun. This whole issue only started with the Preseason, so I'm guessing that League doesn't correctly calculate the MMR (Yes, I know that MMR and not rank determines matchmaking, but rank is a pretty good indicator of skill level) of Players usually playing ranked. If that's not the case and they somehow changed the Matchmaking system, they seriously fked up. I guess I'm gonna take a break from League for now, at least until the beginning of next season, because right now I am not having any fun, although i really liked some of the game play changes.
