Today I was playing on WoWScape and something strange happened. Alliance were spawn killing us at the wyvern master in Gadgetzan, I revived and activated the route to Orgrimmar, but before I did it an alliance priest used Shadow Word: Pain on me. The result was: I died while on wyvern. I was automatically released spirit but my WoW freezed when I tryied to revive. I force-closed my WoW and when I logged back in, I was swimming in the air (like fly hack) on the wyvern route.
Note: I was still dead, spirit form.
Guess it's useless, but someone may find it kinda funny, it could have many uses.
Proof below:
NOTE: It MAY work on other servers, didn't test it.
NOTE2: The speed was same as on normal wyvern.
