I think the developers should implement new quest to give players who completed the quest a Chance to earn free crystals sort of like a tier system. When you finish the first set you can Unlock a second tier for lets say 10 or 5 billion. Yes it might cut down the developers profits but since I've finished the quests I've gotten literally 1 crystal and I finished them a year ago.
Please if youre going to recommend more quests other than spy quest. Please just support the Shark Eb already
As long as we're in fantasy land asking for things that are never gonna happen... How about we ask for an update on when next war season will start.
Leave the attack quest alone it's all set good. But Let's have the devs set a separate quest system for spies
