CC ranking system is simply bad

[Tsugikai]

The biggest problem with the ranking system right now is that it's too easy to rank up to Crystal and you can't derank out of it.
Crystal is full of bored trolls who just screw around in matches because there's no penalty for losing if you're not shooting for top 100.

I very much disagree with the ranking system being "easy". I Have gone from Bronze 3 no stars to bronze 1 with 2 stars and back down again over 50 times since CC dropped.
