If you are ever in the position where you want to be ganked, just do the tower quest in terrokar when its available. I do it everyday and its an automatic camp fest. I just call up my buddies and begin a war, has always ended with me and my buddies on top. Best part was finished ganking a guy n he rezzed and flying mounted but didnt get up high enough and was just standing there. I didn't wanna look suspicious so i just started running around on my mounts until he got used to it when i /emoted him and then elemental mastery 5x chain lightning = gg.

To answer the question, im only lvl 67 and ive already started the revenge fest by making a few 70s log out, killed one guy in gadgetzan when i was on my way to CoT because he was on my hit list. Was taken down by the guards but proceeded to do it a couple of times. When i go out of my way to do it, it doesn't bother me getting killed by guards due to the fact its planned. And i know it must piss him off because it hinders his progress, and he could never hope to kill more then 1 of my guys before the guards kill him.
