As Horde we used to travel from Zuldazar to Drustvar then fly over

I just checked.

As Horde, you still have the instant teleport to Mechagon from the Port at Dazar, but only for characters that have opened Mechagon. Characters that have not opened Mechagon would still have to fly from Drustvar or Stormsong.
