If you are exalted with the Silver Covenant or Sunreavers, and have gotten the quest (Breakfast of Champions) to go out to Storm Peaks for four (4) Jormungar egg sacs, you know that around 50% of the time, a dwarf will spawn instead of a Jormungar. However, if you keep your flying mount button on your hotbar and press it immediately after you finish the drum cast, you can easily fly away if you see a drill pop out of the ground, since it takes a few seconds for them to aggro. However, if a worm pops out of the ground, it will aggro almost immediately.
This is pretty common sense, but most people have not realized it is possible. Plus, it would seem to be an exploit, as I believe Blizzard implemented the dwarves into the spawn chance so we would have to fight, making it take longer to finish. Therefore, I offer it to you guys. Do with it as you wish. (Get the teleporting tabard too, and it gets even easier to finish).
