Since decarding a costume stone cost 50 Fashion Point, i feel like make changing costume for people who likes to change their costume alot be a problem. since everytime u want to change costume, it feels like u losing a chance of getting another stone from the machine.
And Fashion Point is one of the currency that is timegated, which meant there is a limited amount u can get for a period of time, no matter what u do.
i would suggest to give additional option to pay the Price with Zeny,
considering decarding card only cost u 150k Zeny, why doesnt let the Stone getting discarded with 1mil Zeny or something like that.
Since if im in rush, and i dont have any points left, i can just farm zeny as soon as posible, but not the case with the Fashion Point, where i have to sit / play actively 2h30m (considering 10pts / 30min) to just change one piece my costume.
