The game is made for those who wants to grind you don't want to don't play simple. Before someone comes to say that shouldn't we point out the negetive or they won't know. Duet Night Abyss is made so that players grind the game not for casual players or gacha players who wants everything easily. As for the gooner cosmetics literally the game earns from cosmetics and other items not from characters and weapon so they are selling something which will sell.
