I can't begin to imagine the kite job this must've been, but if you take a look at their video of Jaina going postal on Org, you get a sense of just how many people it took. Dipex writes toward the end of the first video that this is the quest-spawned version of Jaina, which I can only assume means they were kiting her from her spawn point in Dustwallow Marsh where the Alliance quest "The Missing Diplomat" ends. This certainly would have simplified matters; getting her out of Theramore would have been significantly more difficult, and I daresay this was an elegant solution. Elegant? Do I mean elegant? Maybe I mean something else.
