Intended or a bug?
Whether this is intentional remains unclear. It could be a bug stemming from all Skyborne starting in the same place. Blizzard has previously been strongly against blurring the lines between Alliance and Horde too much, and the ability would go against established game mechanics. Many players praise it for roleplay and worldbuilding flavor.
For now it works: if you play an elf and meet a Skyborne of the opposing faction out in the world, you can try it yourself.
