Put the room door in personal houses as it once was added to FC houses. Let players who have personal houses buy more spaces to decorate if they enjoy decorating. I know I would buy rooms in my personal to decorate as I really love doing it.

I feel this would take some pressure off people using shell FCs to decorate (which is admittedly NOT a gil-printing RMT-farm problem solution) but this small solution would give reasonable players who enjoy housing for its ostensible uses an extra outlet without leveling alts for apartments and additional FCs.

I suggest to give players the option to add 4 to 10 rooms to their personal at the cost of an apartment each, 500,000 gil (edging more gil out of the economy as a gil sink).
  • 4 additional rooms for a Small
  • 7 additional rooms for a Medium
  • 10 additional rooms for a Large

I'd be interested to see what other people think!
