I’m all for more of that other stuff but the thing is all that stuff is done by different dev teams .
There is a team for dungeons and raids
There is a team for pvp
The is a team for rewards like gear and weapons
There is a team that works on the open world
There is a Team that works on Classes
There is a team that does housing.
All different teams so in all honesty housing has no affect on whether or not there is or isn’t more dungeons then 8 at the start of an expansion . That is what Blizz has decided on for the last few expansions so that predates them deciding to add housing .
As for PVP they gave up on Battlegrounds with Legions Seething Shore .
So you are going to say Housing is to blame for no new BGs even though there hasn’t been a new one for the last 4 expansions .
