I find it unbearable that this expansion had pandaren thrown in straight from the start in its cinematic (as if though we weren't gonna see them freaking everywhere else), while Gnomes, Goblins and Worgen have yet to have their moment to shine. I would've liked to see that pandaren do kung-fu against an angered Worgen who would've probably ripped its throat out.
That aside, Gnomes, one of the Alliance's most important race (gunships, steam tanks, all its siege explosive capabilities) have been eluded the longest, and they need their moment to shine.
