The Forsaken are busy doing their own thing, as they always have. Vol'jin and the trolls were last seen sending emissaries to the Alliance to help contain the Zandalari. The tauren are still mourning Cairne and have little love for Garrosh. The blood elves lost their reason to stay in the Horde at the end of The Burning Crusade and seem to be sustained solely by inertia at this point. The only loyal Hordies left are the orcs themselves and the goblins, a race long known for their steadfast loyalties.
Of course, the Alliance isn't all too chummy, either. What do you think? Do the races need new battle cries, or will Mists of Pandaria spur a new wave of unity?
