Phasing System

Recently, I was looking for a home for one of my characters in Pandaria. The trouble with that is most of the houses are already claimed by Named NPC's. And because of this shortage of houses for players, I believe that a phasing system for these places should be implemented to give the player(s) the houses they want without them still having lore value to them, via being in some other part of the world just in this own personal phase, be their own home in some other part of the area they are in. This would also help to expand how large the world is, compared to what we actually see in-game.
