Yeah, unfortunately adding Goblins to the Horde has taken away their sense of neutrality, but the fact remains the bulk of their race is still neutral, and Undermine, the wealthiest, largest and most powerful economic hub on the planet is somehow inaccessible.
Alliance characters could have Renzik “the Shiv” and Grizzik as their focal characters. They’re both Alliance-loyal and have been around for more than one expansion.
I should say that I’m not opposed to the idea of an expansion set in Kezan–it’s supposed to be destroyed, but then, so was Suramar. I’m only opposed to Gallywix as the Big Bad.
That’s would be a waste. But Kezan is only a small part of Undermine.
