As for inflight inconveniences, I would LOVE that. As someone who loves to fly through the air and swoop down through the trees, I would be fine with interaction from the ground or sky. There are already Giant Plainshawks at HalfHill (nerfed), rocket turrets in Krasarang and Storm Peaks, a player object than can dismount you (if you are within range), and more. Plus, if you think about it, there is no good reason why our drakes don't breath fire, or have the ability to eat NPCs like the sourge mount you ride in the final sequences of the DK starting zone). Eating an NPC (hostile) could replenish energy, power, mana, etc. You could open up a world of possibilities rather than shutting them all down.
