At this point it is all speculation. We already know what PT1 had in store. Compare it to the Draenor pathfinder, and then fill in the missing elements. Voila. Now you have PT2 figured out. It is not rocket science. It is a video game achievement, and not even a complicated one.

Pretty sure they are familiar with your rhetoric. It's the same basic post every other time in this thread and the mega thread. Flight is being unlocked, and the meta should be easily attained. Not much to discuss, yet your statements still sound like you are admonishing Blizz for not doing it sooner and for infracting the civil rights of players.
We're getting flight. We'll get the details about 7.2 soon enough. Not sure what else there really is to say on the subject of unlocking flight.
