Its crazy that after collecting 10 blue rocks to get a wonderous crystal chest, u open the chest to get ONE wonderous crystal!
Kabam pls improve the drop rate 1 per chest will take a life time to elevate one building and eternity to do all cities!
Or at least give as a way to win them again like in merlin chance or madness.
I have x2 divine elevation and I can't use it because I need 250 to elevate and one a chest will take half a year!
