Today MMO Champion put up a few maps that have been datamined. One especially caught my eye, the 'Lightforged Draenei Swamp', which I recognised from else where. Have a look at it:
And now look closely at the Zorammarsh in Tanaan (Centre Bottom of the Map):
That's pretty much 1:1. Except I think that Draenei building on the right is new.
So the question going forward is, what do the Lightforged Draenei want with Zorammarsh on Alternate Draenor? It doesn't seem like an ideal place to set up shop. If it's not Lightforged Draenei related like the file name suggests, I still don't have a clue why they'd make a zoomed in map of Zorammarsh just for the hell of it. For whatever reason we're going back there in BfA in some capacity.
