Couldnt think of where to put this so I decided to put it in guides.
This is just a lil trick Ive been using for a while on my mage in Tanaris. Just sit in Gadgetzan and place a campfire down. Then use some seemingly friendly emotes like /silly and having a drink so the "you feel tipsy" thing comes up may help. Sit next to the fire and when some horde/ally have come then you AOE em, and because its Tanaris its mainly lowbies there so you will be able to kill em with ease.
Also because ZF is nearby the lowbies there will come and go, making this repeatable rather easily. No real gain but if your a ganker (like me xD) you may find this helpful. Basically you gain their trust, then abuse it.
