An excellent guide!

I have a quest suggestion to add for the Alliance side for future versions (if you're planning any). When you turn in the Thadius Grimshade quest in Nethergarde, pick up the Fallen Hero quest from the Blood Elf NPC in the same room. You turn the quest in at the Fallen Hero of the Horde NPC who is at the border of Blasted Lands and Swamp of Sorrows, only about a 30 sec run, and you get 19K XP, plus another 2700 or so for the follow up which is just clicking through some dialogue.
