Matchmaking is the worst its ever been

With this new rankings based on roles and not overall ability to play the game has led to some of the worst matchmaking that i have ever experienced period. It is not something new for teams to be unbalanced and having bad teams this is not what this is about. It is about the fact that a gang plank player with 100% (used to at least) got into gold mmr and that was alright placing in silver IV and climbing relatively easy on top lane. But ive never seen such bad matchmaking in any competitive game before at this lvl. I am not to high at Gold IV but being paired with bronze IV and Bronze I players is kind of interesting. The matchmaking is so bad its actually insane you have diamonds on my team shitting on lvl 30 lux supports that buy dorans ring as a started item. This is by far 1 of the worst possible changes they have possibly ever made since they dont know how to manage it.
