My suggestion is to add some kind of quest or something, that would allow us to unlock the ability to teleport to specific aethernet locations within a main city such as the guild aether crystals.

By this I mean when I open the teleportation menu and mouse over Uldah a flyout would come out listing all of the locations available within that cities aethernet, and I could choose to pay a little extra to go to that location.

But I think this should only be available after either unlocking all of them in a city, or having some sort of extra quest to do to enable this function.

Hope you all like my suggestion.
