My FC leader and I often muse that it would be fun/nice to have a new form of instanced housing called "hermit housing" or something along those lines; it would be a system that would allow you to pick various locations into an isolated housing instance. Some old ruins in the wilds, a lonely tower on a snowy coast, a yurt on some floating rocks in the sea of clouds... you would unlock the location and build/refurbish the structure and then decorate. It would be a great DoH/L required way to have another housing option. Lower server demand by making it count as the one house you are allowed to own (thus also freeing up more housing for those that like the more social neighborhoods that are Housing Wards).

It's just a rough idea.
