I would also guess this is going to be similar to the Draenei starting zone experience moving from Silvermyst to Azuremyst Bloodmyst, except it encompasses fewer levels; information from the preview panel indicates that the new Goblin and Worgen starting zones encompass levels 1-15 instead of levels 1-20 about
power leveling.
The Lost Isles appear to be the focal point of the early Goblin leveling experience, and so far they look beautiful; a lush, thickly-forested landscape northeast off the coast of Durotar and southeast off the coast of Azshara, now said to be retrofitted as a "Goblin zone." I would assume that your introduction to the Horde will occur here. There is evidence of some crude huts and a makeshift marketplace as well ¨C it is obvious that the Goblins have not been an established presence there for very long about
power leveling
In all likelihood, Isle of Kezan Lost Isles Azshara is with Stonetalon possibly along the way, or after Azshara. In Alex Ziebart are words: The Goblins have carved out Azsharas mountains to build their town. It is really ugly. Yay, another Horde is race that brings the ugly.
Undermine is implied but not confirmed by the new information; truthfully, I am not sure what to make of it. The storyline would seem to suggest that the Goblins can not stay on Kezan, period, which is where Undermine is, so I am unsure what happens there.
From what is been spilled about the storyline, which is said to be heavily phased to get
power leveling, I think you will level here while the cataclysm is ripping the island apart, then board ships that get caught in the crossfire between a Horde/Alliance naval it and wrecked off the coast of the Lost Isles.
