With the new working /sit /stand lag macro you can use this to get out of wow faster than normal logouts! Just click your macro as fast as you can and you get disconnected. Why wait 20 secs just because you are outside an instance somewhere when you can logoout and skip the char screen in a snap! You can say if you are horde run into IF and use the exploit to throw off players, run somewhere and type /pvp to unflag yourself, then disconnect faster than logging, when u log back in in a few minutes, you are non pvp in IF!! just be careful of npcs.
Heres the /sit /stand lag exploit
