Fix your MM... by split into two groups... GM and BM islands... really easily

Fix your MM system please... put all trollers and other kind of negative players into the island of BM therefore everyone in BM island will queue with other BM players until they learnt their lesson.

I am already fed up with BM players in the rank... it was so difficult to play solo in the rank with GM players. I don't want to stuck in the BM environment forever.
