This is probably common sense, and I tried searching and couldn't find anything related to this. It only really works with classes that have a taunt or some way to rip aggro from everyone else.
Basically, what you do is when your group is about to kill one of the bosses in AV (depending on your faction), use your taunt and pull the boss outside so he/she resets. I've been doing this lately and it's pretty hilarious, especially when everyone's screaming and crying about it. Don't overuse it though or you could probably get a warning from a GM. Just do it every so often and if a GM happens to message you, just say you were getting used to your new keybindings and were accidentally hitting your Taunt ability You could also say your baby son or daughter was on your lap and slamming his hands on the keyboard.
Hope some people find some fun out of this :wave:
