If you could add 1 item to the mog station.

Bahamut flying Mount most definately.

Or an Infrit, Titan mount.

If there is ever a case where we will be allowed to swim then a leviathan mount.

Zero's hairstyle n outfit from drakengard 3.

[UnstablePersonality]

A retainer with a little free purchase button under it.

I would add something that removes the cash shop and all history of its existence.

People wanting job unlocks on it now reflect the usual cash shop content trends. Starts out small and innocent, and before you know it you're buying exclusive vanity, then eventually actual playability.

fenrir, to bath in seas of salt and tears

Wouldn't mind if the top 2-3 (each gender) runners-up in the hairstyle contest made it into the mog station

wants to buy "Sarcasm off" button.

I want the Cait Sith minion in the cash shop. T-T

I'd also love a Bahamut flying mount that looks like FFX's Bahamut.

I'd be more than happy to pay cash for a Yuna costume, as well. FFX and FFX-2.

Well it would be fine if they took all the stuff people suggested and put it right into Mogshop.
So far I am pretty addicted (around 200 days playtime since August 2013) and find it impossible to leave the game for good, this would help me a lot.
Mogshop was going slowly untill recently (2 separate Mogshop additions during one patch) and I didn't mind that and even bought from it, I am not really surprised by the increased effort put into Mogshop, but I am definitely not glad about it. )
When you see new mounts/glamour stuff in Live Letter and the first thing you think about is if they are going to be in game or cash shop, that proves there is something wrong, especially when talking about subscription based game.
