There sure were a lot of jokes about Garrosh getting milked.
This video is very well done. It's always fun to get a video from the point of view of the bad guy being deliciously evil.
Revendreth seems interesting as well. It looks like the equivalent of a Hell, where evil souls are tormented until they repent. It is amusing that WoW cannot use demons for this traditional role, because demons occupy a completely different place in WoW's cosmology. Instead we have anima-drinking vampires (or possibly elves).
The only concern is that this story seems a bit like the Suramar storyline in Legion. Nobility hoarding a resource that everyone needs to live. There's probably going to be a revolution as well.
I just hope it doesn't end with Garrosh yelling "Revendreth is free!" at the end.
