Edit: Got a few comments about people claiming I knew about this bug and was pretending not too. I have since seen the movie explaining how to do it but at the time I honestly never knew about it we were messing about around the nagrand arena then it happened and we couldn't figure out why. One person logged whereas I thought i'd be a bit more inventive with it.
So enjoy some randomness including mid-air duels, flying pvp, meleeing flying mounts, killing shattarath guards and more aswell :p
I reported myself to a GM and explained what happened and it was fixed but before that i had some fun with my new abilities :p.
