I wanted this expansion as well to be called "Rise/Reign of Azshara" as Expansion name and not "Battle for Azeroth" and that all this faction wars would be avoided, brings me a bit confusion, while if it was "Rise of Azshara", they could expand the maps and not just have a single "Nazjatar" map.
Here's the concept i saw that i think it should make the expansion @

Even has Kul'tiras and Zandalar, i would have preferred this a "new dalaran" in "Zin-Azshari" where both factions could be with each other still after Legion.
