Yeah cc is dead, mostly around all DCs. Even at high ranks, hardcore pushing players are not even playing anymore.
Im from aether, but even around Crystal DC is not even popping around high diamond-crystal.

I hope you can get a nice pull of players to achieve your goal, but i said to a friend last patch, if they are not making good enough changes (this mean not a new map) CC Ranked is dead for sure in the next patch.
Im already planning to quit until i see a resurge of players and ive been playing a lot of CC Ranked since season 1.
