Player housing opens up a load of cans of worms of allowing a lot of player customization. Blizzard pretty much hates that, and what little we do have has been the most basic, worthless version of it. It's pretty much clear that this has never been a thing Blizzard has ever really cared about, pretty much in any of their games. Certainly not the one where it'd matter the most. I mean, hell, the character creator in WoW at launch was even bad and restrictive for it's own time.
Don't worry, though! I'm sure there'll be lots of raid and dungeon instances with RNG on RNG on RNG on RNG on that RNG. Who needs character and immersive worlds in MMOs when you got instances! WoW is an arcade game with typical MMORPG-type combat with a gigantic lobby, pretty much.
Anyways, I think player housing is too late for anyone to care. I'd like it, I have zero faith in Blizzard being able to do it in a way in which it'd be beneficial to the game, as it's obviously not something they've ever cared about.
