Events are bad. Finishing them requires spending gems or money. Progression is unbelievably slow unless you want to buy those overpriced bundles. They make watching adds almost necessary if you want to feel any kind of progression. absolutely have to watch ads for upgrade items. Edit:the main issue is progression. In the event now, it takes 45000 to purchase a piece of equipment. I got 8 turns. Max 150 per turn. 45000/22days = 2045.45. Need gems or money to get 45000. Pay to play
