So long as we all agree that it is 100% subjective and that the only change that has occurred due to the removal of flight is increased time requirements, they can do whatever they want.
Edit: I'm posting this while doing my Draenor pet dailies. Because there's no flying mounts, I use flight paths to reach them. Instead of traveling through the zones under my own power, I'm taking automated flight paths... and since they're automated, there's no point in paying attention until I land. So immersive.
