I'm late to the party but to me the issue with housing is not much an asset issue or even some UI issues.
These are the two main issues I see :
* Location and access : give some liberty for the player to choose his housing location and not have everyone overlap or go in garrison style housing : phasing where you need to indicate in the menu which player housing you want to visit which breaks immersion. FF XIV solution to me is one of the worst, having instanced neighborhoods bringes nothing of value to the immersion.
For instance, if every city in the game could have a few houses and if you could settle in one of these or if you could even set up shop next to the ravenholdt manor or waycrest manor. Then on a small populated realm, it's all good and fun vut you rarely see any player housing and on a very populated one, it's a diabolical mess.
* Housing reward and drive : A game like sims or animal crossing have the housing at the center of their gameplay. how do you spread the reward else than "reputation can sell you a chair, a table and a lamp". What use is there to invite a player to your home? Do you limit it to a house per guild or per player? if guild, then who can modify it? What different interaction with the world does it make to be in this or that location, to have this style or that style of house to fill it with this rare piece or that rare piece, to have this utility or this one, etc.
There are thousands more questions that goes into what to do to do it right, and from looking at it there is no right answer for the first issue and I can only trust blizzard to find some new way of gameplay and reward for the second issue.
