We just found a new out of map glitch.
Its a bit harder to recreate since it requires a bit of bad luck and nitro boosts on your belt.
Go to the Halls of the Eclipse in Suramar in the Felsouls Hold area. There you have to take the first steps down to position 27, 88Use your nitro boost belt and hope that it fails and launches you into the air. Repeat this step until it fails.Use goblin glider or whatever you likeMaybe someone finds a use for this.
