It's so entirely ridiculous. You go from being one step removed from being a trade prince/princess, survive the destruction of Kezan, being stabbed in the back by Gallywix, save your people at the Lost Isle, meet the orcs, save Thrall, build a town out of an explosion, fight a giant robot chicken, fight some naga, fight off some old god related terror, fight a giant shark with Goblin-made frankenstiened shark submarine with missiles and lasers on its head, fend off the natives who are kidnapping and turning your people into zombies, fight a giant volcanic turtle god, fight off the Alliance, fly a plane and blow up gnomes in the sky, save your people from Gallywix, defeat Gallywix, are key in the Bilgewater Cartel joining the Horde and then you go to Orgrimmar. It's such a dramatic step down ending up in the Northern Barrens or Azshara after all of that.
