This game is getting more worse and money-grubbing as it goes on. Gameplay has been left by the wayside in favor of making the graphics shiny and pretty (and glaringly eye-hurting) and getting users to buy as much goods as possible. On top of that now, they're adding another gatekeeping level of card upgrade that is favorable only to those who are throwing insane amounts of money at this game. I really can't with this ridiculousness. Like other users who have commented, I miss SuperStar BTS.
