An interesting idea would be what if you owned an inn room and could put furnishings in it like you could a mog house in FFXI. Simple way to do it would be, the Grand Company you are aligned with gives you your own room it could a reward for getting to one of the unreleased ranks. From that point on when your in that town the room is yours to put whatever furnishings in. The room is very small but at least we can play around with furnishing some.

That way people could sell a lot more stuff on the market. As it is now any free company that buys a house will obviously have a lot of crafters at max level so they can just make anything.
