Objection, calls for speculation. You have no way of factually knowing there would be an overwhelming response for flight. Also, there is no way to add a poll (unless something has changed on their site).

What I saw was an orc attack a flight path gryphon (which we can do in game), it fought back (which it does in game), and it died (also done in game). He was not using his flying mount for combat, aerial or otherwise.

The first 25 seconds were flight paths through Dun Morogh, Deadwind pass, and Dalaran. It was not some rogue on a firedrake raining down destruction on a dire wolf.
