The game is not in a good place. They havent released any fun engaging content since team ups. It takes them months to release new characters. Not that it matters since they give you so little resources that even saving all that time wont get you enough. It also doesnt help that a new character drops with a card banner and both need 100 summons to reach pity. Even buying the currency doesnt get you very far unless your spending obscene amounts of money and its really not worth it imo.
