How about I’ll bookmark this and come back in about a year to laugh at you? 
Blizzard copies other MMOs. They’ve been hot and heavy copying GW2 lately with the new mount systems.
They’re definitely not going to NOT copy other popular MMO housing systems for the same reason. I mean, how long have you followed this game? It’s what WoW was always known for: rip off other franchises and polish up those systems and make them feel snappier.
This won’t be any different. It’ll be ESO-style or GW2-style housing. Wait and watch.
