anything on the mog station actually worth the money?

skip the story skips unless you really just need to catch up with friends on current content. the story is half the reason people stick with this game, and you can't easily go back and feel it the same way.

fantasia if you're sick of your character's look, that's the one people never regret. extra retainers if you craft or gather and your inventory is constantly full. most of the rest is mounts and glam, which is fine if you like them but none of it changes the game.
