MMR isnt working Riot!
It is so boring, to play every single game with people who cant look at the map and people who refuse to listen to ping to be careful and back away, all they want to do is fight all game and not react to turret been taken or react to objectives being taken. People who refuse to play as a team and ward the map.
If you arnt interested in fixing the problem Riot, then dont exspect good of great reviews on site.
