I can't remember where exactly it was, but I'm pretty sure I remember them mentioning (two or so years ago?) a possibility for new (most likely) additional fee-storage to be added if they get the okay for it... but I don't think they mentioned it ever after.

I wonder if it's still on the todo-list.

I've never used the wardrobes that require an additional fee so far. I still manage to keep equipment around for mainly SAM, NIN, and THF, but if I still actively played RDM or some other magey type as well... I'd definitely need to play with the storage slips a lot more than I do now.

I keep a lot of useless stuff around too though, because reasons (definitely might need /this/ thing on some adventure!), and a lot of it is non-equipment stuff as well, so the wardrobes lose usefulness to me there.

And yeah... my Mog Safe is literally full of furnishing, of which all but a few are event items and statues. Mog Safe 2 is nearly the same, with a bunch of non-event items included. Floor two looks like a yard sale (or something like that) someone once said.
