Really impressed.
It set the scene perfectly in my opinion. The war between Orcs & Humans (Horde v Alliance if you will) found it's way to Pandaria, both sides came into contact with the Pandarians at once, neither looking any more good/evil than the other (they were fighting and both chose to fight the Monk) and eventually ended in awe of the beautiful civilization they stumbled into.
Quite easy to infer what happens next. They go into the Village, drink some beer eat some food, and gather groups of followers, eagle to explore the world. Resulting in both Horde and Alliance Pandaren.
Couldn't ask for much more really...
