Yet another steam tonk exploit, I did search but couldn't find anything about this.
/use Steam Tonk controller
/use Portal: Shattrath (you can also use hearthstone)
/use 13 (PvP Trinket that removes the stun in your top trinket slot)
Then manually click your mount and stop casting before you mount up.
Quickly take a flight path, the gryphon should change into your mount and carry on the same path, pretty fun to watch
I'll post a video if necessary.
