I am on the beta. So I know there's know "morally grey"area for Sylvanas. Thanks mostly to bad writing. She was a compelling character who seemed pragmatic and emotionless. But she did that in a rage after being confronted about her actions. She was just going to occupy it. Every freaking no soul Nathanos did a freaking double take. A lot of horde players are mad about having to basically be complicit in it when they weren't when Garrosh lost his bleepidy bleep.

The Saurfang scene almost made up for it though.
