Why do you think they’ve been “streamlining” and dumbing down everything ( even more than usual ) the last couple years? Consoles are the last ditch go-to for milking dying games.
Yes I know all of that.
My point is that WoW is developed in a way that requires add-ons for a lot of content to even be playable.
If WoW can’t have add-ons then it wont be ported to console. It would need also away to host add-ons and traditionally WoW has never promoted/hosted individual add-ons like Skyrim does.
