I think what you guys are doing right now is driving this game to a dead end.And it is not a good idea to change the reward for leveling up from crystals to just a container.And now the containers are terrible,there are fewer props and crystals that can be opened,which is terrible compared to before.I even want to quit this game,it is not worth wasting so much time on it.If you change it back,I will keep on playing it.
