WotLK was insanely good. I would say that Legion is also stunning. Unfortunately, it loses me when Varian swims up out of the water with all that armor on, and then the "For Azeroth", which seemed trite. But up to that point, I was mesmerized by the quality: the look on Varian's face when he saw death during the ship's descent, and the oh-so-subtle nod that Sylvanas gives him as the ships pass. Incredibly good. Writing (his note to his son) a bit of a let down and cliche, but overall a big quality jump from the trailers since Wrath.
