Unless I missed it, reading over the datamined info so far for archaeology only shows that they have sub-sets of Orc Clans that you can do archaeology surveys for.
I'm a little worried that Archaeology in WoD is going to focus primarily on Orc culture and, once again, ignore the Ogre and Aarakoa Archaeology potential. It's especially worrisome since it's clear that this new generation of Aarakoa will be more culturally advanced than the previous ones from BC.
And what about the Draenei? Do they not get an archaeology "clan" in WoD as well?
I mean, say what you will of Pandaria archaeology, at launch it was distinctly divided between Mogu and Pandaren when it could've been distinctly Pandaren-driven. :P
Now I'm rather hoping that if these other cultures don't make it into launch that perhaps they'll include them in post like they did with Mantid Archaeology - so long as they add them is all that matters to me.
