Unreasonable? Most often I'm out of the country in 2 week intervals. I'm sorry about I'm not using my house in that time, but playing FFXIV when I'm in another country from a hotel just isn't feasible. And then there was that time I was the sickest I'd been in years a few months ago the prevented me from playing the game for over 2 weeks. I'm sorry that I'm sick and not using my home, but life happens that I can't control. FC homes don't perform any vital functions so FC don't need homes anymore then anyone else. And especially now, in this world crisis, 2 week demolition times would be absurdly cruel. It's not like the housing demolition process is clean, I would be looking at weeks of decorating lost, 40+mil in furniture now wasted, 12 mil lost from losing the home and the sudden need to store around 700 furniture items before it gets tossed in the virtual dumpster.
With a 2 week timer, I'd have to give my password out to someone else just for me to travel abroad, which is against the rules. But that would effectively be my only option to try and save my house.
