They keep adding it because people keep buying it then heaping praise on them for releasing one of the best expansions in MMO history. Square Enix is pretty arrogant right now for a good reason and is obviously cashing in on FF14. The amount of Mog Station stuff has been put on steroids.

If this expansion sucked you would not be seeing this really but game is popular so whatever.

Square Enix does stuff that makes NCSoft and Bethesda look like AMATEURS when it comes to monetizing players. Activision would KILL for this playerbase that allows it without batting an eyelash.
