As per my post on Facebook:
I actually really liked it the first time. It captured what WoW is: a lighthearted, fun to play with conflicts between the Horde and the Alliance that is focused on the home of Pandaria. I think they did a wonderful display of everything they wanted to touch on:
Strife between the Alliance/Horde, the introduction of the Panderan race and the world of Pandaria. It's a prelude of what's to come.
I give it thumbs up.
