Suggestion: Dynamic Interior for Housing
I would like to see FFXIV update the housing system. Yes, there needs to be more wards, but this isn't for that. :)
Regardless of size, add options to the housing to make them more dynamic and different. It could be a great gil sink.
Allow the user to move the stairs, the interior walls, etc for a gil amount. If you want to add another lower floor or upper floor? Make it cost gil. Add a working balcony? Make it cost gil. Increase item limit? Cost gil.
Let us design some unique houses where the only limit is our imaginations. :)
