I have no problem if it’s just cosmetic stuff. But if it gives advantages in PvP then it’s a huge problem.
I do disagree with stuff I saw in the news that people tried to get the ESRB to call it gambling. It’s not. You’re getting something in return, unlike playing video poker or craps. To me it’s no different than buying baseball cards- you’re getting stuff but may get a lot of worthless cards.
