I dont care much about player housing. But I would like a account wide reagent bank instead of sending mats between characters by mail all the time.
However, most people who play the game care mostly about pets, mounts, transmog, hairstyles etc, so I assume that housing would bring more people the game and be fun for most people in the playerbase.
So I don't see a huge problem with implementing it.
Also, the best MMO after WOW which is SWTOR has a very extensive playerhousing where its basically like playing SIMS in the game where you can move furniture around and hang up paintings and everything. Seems to be quite a success there.
