Opinion:
Blizz should continue focusing on endgame content. However, they should revisit old areas and story arch to make them relevant again. This way the world feels more connected instead of fighting in an isolated area
The expansion is called Battle for Azeroth. Yet it basically is the Battle for Zandalar/Kultiras. Yes, we do visit older areas (arathi, darkshore) but it all feels disconnected.
We shouldn't just jump ship every expansion and abandon a whole continent for a shiny New one.
All the other continents should reflect current content. Although I can see how this would take too much production time and effort. But it would be nice nevertheless to see azeroth (and outlands/draenor) feel whole.
