To everyone complaining about the 11/15 ranked reset...
This is preseason. Whether you went up, went down, or didn't move at all, it doesn't matter. Your rank will be reset for season 7.
Your MMR affects your season 7 placement, not your rank. And the matchmaking (now that they fixed it) is based on your MMR, not your rank.
It's like you guys are complaining that somebody replaced your good mattress with a bad one, except you're in a hotel and you'll go home soon. Stop complaining and realize your preseason rank won't matter soon.
Peace.
EDIT: If you don't get placed low, how can you climb anywhere?
