Not a bad fake trailer, given the source material, which ranges from a commercial for a medieval festival to big-budget movies like The Hobbit and Thor: The Dark World. He's even got some Warcraft 3: Frozen Throne cutscenes in there for good measure.
As a long-time player of the MMO, it's all a bit too dark and gritty for my tastes. I was drawn to the game by its bright colors and cartoon aesthetics. I'd love to see something more along the lines of classic 80s fantasy, with bright hues and giant shoulder pads. I would not be averse to Muppets. I might pay extra for them.
