We have still yet to see the Corrupted Druids that were shown in the artbook as well as the slideshows they showed at Blizzcon those many years ago, I can not locate the pictures
Skovos is also coming, the home of the Amazons.
(Death by Snu Snu)
If the necro is coming in it makes a lot of sense, since Ureh was shown in the trailer.
Also, if these two beautiful creatures are not in it, I will riot...I've waited...12 YEARS OF IT.
