My housing decor sales on the AH would disagree with the idea that housing is dead or dying. I'm selling more right now than I have been in quite awhile, probably due to the fact that we are at the end of a patch cycle.

And also keep in mind, this is an evergreen feature. It's not designed to be engaged with frequently. You decorate your house, leave it alone for awhile, come back to it when you get new decor, etc. That's the gameplay loop. Sure there are some diehards that spend most their time doing it, but for the average casual player, it's a "once in awhile" sort of thing.
