Rediculous and Unfair reroll daracron，it's cheat

It's not cheating, it's gambling, easy as that.

Eventually legislature will catch up with this, but until then you'll have to endure.
Alternatively you could speak to your credit credit card provider, if they see this similarly. If enough people complain, they might start flagging this stuff as gambling without waiting for legislators. At that point, it will stop immediately.
