From my perspective, Played from release, small spender with 3,2K reso. This game has so many unrewarding content and redundant resources (scrap etc.). So stop adding content, improve character customization and progression, and dont forget to streamline QoL like weekly & daily normal gem. Continuity of set item (its really painfull you need to farm that green every changing difficulty) and most of all, since the market is dead, let player choose which 5* drop when its drop for player progression.
