I personally don’t care about any peacocking with player housing.
I don’t care about any customization of player housing.
All I care about is having more stuff to collect 
It doesn’t even need to be player housing, Blizz could add rock collecting and I’d do it 
‘Collected all the unique rocks from Durotar’
‘Collected all the unique rocks from Kalimdor’
‘Collected all the unique rocks from Dire Maul’
