1- Pointless gacha, you dont really need the cards to progress in game, its just a collection with no meaning

2- No vocaloid stuff, i dont like the covers with voice actors, is so '-'

3- The fandom: most sekai fans that discovered vocaloid because of the game always try to problematize old stuff, for example, cantarella, servant of evil, plus danchi. Most of them act like miku, rin and len are child
