I had a good one happen this weekend.
I was on a windrider going to Ferales, and when i reached the docking port instead of getting off the windrider, I stayed on it and was able to fly about as if I was on a flying mount.
I stayed on it and flew about circeling around people and freaking them out, because of course they were wondering how I got my flying mount out of the outlands
In the end I just had to choose dismount, and I came back to the ground again.
Was funny though
