On the other hand, they have centralized the portals. You don’t NEED to go to those other cities. Your Dalaran hearthstone puts you a 30 second run from the portal to Orgrimmar, or a 40 second run to the portal to Stormwind.
So there is no “all the way to”. How often are you closer (closer than 60 seconds) to some other city?
Those 2 city portal rooms have portals back to BFA, or you can use ANY INN as your hearthstone. ANY INN is much better than ANY MAIN CITY. And you can reach the toggle war mode place in less than 1 minute from anywhere.
So…WHY would changing the rules to “any city” make anything faster or more convenient for anyone?
