I could have worded my post better but I didn't mean to imply that I couldn't understand why housing keeps people subscribed. I meant that when compared to the current retention mechanisms WoW already has, I fail to see why adding housing to that would be beneficial. This is because, as I've stated in other posts, I feel like WoW's current gameplay loop doesn't seem to encourage housing.
I restated my argument because I thought you had misunderstood my position but I see now that the misinterpretation was on my part. Apologies.
