There's nothing wrong with selling cosmetic items to begin with so I don't have any idea what you're getting at. Some people really like that stuff and don't mind paying for it and it frankly doesn't matter if you don't like that. You're not a part of someone else' transaction. If they're happy with what they're receiving then there's no issue.

No one is forcing you to buy cosmetic items and the game isn't being harmed elsewhere. There's just nothing to complain about. Needless negativity for the sake of bitching.
