Houses are being dedicated to furnishing storage and de facto "IKEA" set-ups in several guilds I am in, due to a build up of furnishing over multiple cycles of building -> tear down -> reconstruction. The older the player, the more furnishing items it seems they have gathered and cannot get rid of.
Deconning would be a great solution to the huge amount of furnishings that aren't easily sold or given away, and would be super helpful in the gathering of hard-to-find materials like mundane runes and decorative wax.
