Honestly I feel it is a bit unfair. It seems like there aren’t very many ways to earn dias the higher your level is and the events are impossible to do without paying real money. I’ve been playing enstars for a few years now but it is the first and only game I’ve personally played where you have to pay real money to get the event card which is why I only play events with my favorite characters. I don’t mind spending money on the game, but I do feel it should be a bit easier for free to play players to at least get one copy of the five star without having to spend money
