I think individual apartment units for players who don't have a FC where they can purchase a house but who still want to decorate things would be an acceptable addition (plus the new Ishgard housing wards.) I was thinking that was the plan with the Habisphere in Azys Lla, but perhaps that was wishful thinking. A room the size of a FC personal room, with a small (outside) balcony that has room for a garden and a chocobo stable, and which can be accessed by anyone on your friend's list that wants to visit, or anyone who is in your party (like how it worked in XI.) That way the UI doesn't become insanely cluttered. There could be a central lobby area with a market board and summoning bell, and when you teleport to your "house" you land there, giving a communal social space.
