We do allow players to access our endgame content quickly through chests and gems.
We understand the sensitivity around this practice and because of that, we will be constantly tuning and adjusting the rates and rewards. Our use of these practices will be closely monitored in order to have a healthy balance between keeping the game fun and exciting and to help keep the game running.
Your feedback is welcome and please expect things to change with each update as we continue to improve and experiment. Our up-to-date chest drop rates can be found in-game.
