Yeah, there's a similar one for the Wildhammer and it's definitely soloable by most classes that can solo an elite. You take out one of the other faction's elites, iirc. You guys have to take out a shaman and we have to take out a warrior. And I don't know what that shaman does, but the warrior will chain intimidating shout you. It's fun. (It actually is pretty fun, really. As long as he doesn't fear you into an add that has instant respawned.)
