As someone who just started decorating my room in our FC house, I can understand how attached we can get for the hard work we put into decorating our room and house. it takes time and effort especially after a while when you start farming for those more expensive furniture.

As some posters have said do not forget to reclaim those from the housing vendors so that at least when you re-acquire a house or room that you at least have those rare furniture still.

I do wish they can think of a better way for this housing but it is hard. Even if they make it an FC only housing some people will make shell-FC to buy multiple ones.

The only thing we can hope is like you said that people can be more reasonable and generous but unfortunately for every generous person there is a person who is not. I once met someone when I was helping FC to buy a house in goblet who said he was buying a house not because he wants one or his FC needs it (they already have FC mansion), but because they are planning to make an entire ward under their FC so each member is encouraged to buy a plot on that specific ward. And yes he won the click race lolz It is kinda sad though as after I congratulated him he admitted that while it is awesome he won he probably won't use it much since he is not a housing player.
