It certainly drips with that Vanilla WoW flavor. It's probably the lack of shoulder pads.
One thing about this video is that it really gives a sense of many different smaller stories happening. A modern WoW expansion is really focused on one major story line. Now, Blizzard does a pretty good job with that one story line, but I kind of miss the old way where each story was somewhat separate from the others. I suppose Pandaria was the last expansion like this, at least before the Garrosh story kicked into gear.
