It’s fine if you don’t understand that not all the cities are made equal. It is not convenient to use the non current hub or our main city SW/Org because they lack the features of the main hubs.
I personally don’t want to play portal jockey in order to be able to use Silvermoon as my hub for example. Silvermoon you can’t move around quickly either as it’s still grounded mounts only. There is no barber, no void storage, no transmogrifier etc.
There is little point in using UC at all now (even if you go back in time and use the old version) and even the heirloom vendors moved to Orgrimmar.
I essentially spend most of my time in Dazar’alor or occasionally Orgrimmar. With my two engineer characters I don’t even need Orgrimmar for the AH any more.
The point I was trying to make, which I’m sorry wasn’t clear, is that it would be nice if all four main capitals were equal and had all the same services and portal connections. It would mean there was more choice of what base people wanted to use with the same conveniences and hubs wouldn’t need so much sharding.
