Broken Ranked System
Ranked System needs different scoring system. Your ranking score is based on whether you win or loose. If you get a bad group or troll then you loose game. Which means if you are a team of 5 vs single player you'll never get anywhere because you can't come back from early feeding by troll or bad group in general. Fix the rank scoring system or at least matching system so player doesn't end up with constantly with a feeder/afker/troll.
