This is a very easy trick if you're a warrior. Other classes might have some difficulty, but this works like a charm for warriors.
1. Go Defensive stance and taunt a kobold.
2. Bloodrage, then use Demo Shout and aggro more.
3. Go Berserker Stance, put up Berserker Rage, and wait for more rage to use another Demo Shout and aggro even more.
4. Make sure you have an AoE or cone damage trinket equipped. (Eternal Essence of Eranikus, Smokey's Lighter, etc.)
5. Face the kobolds and watch them all DIE...
Sorry if this has been posted before, but I love doing this and all the lowbies shout at me when I do it..
Enjoy!

P.S. If this isn't considered an exploit, sorry, but it's really fun to do.
[Edit]: Ok, ok, maybe not alliance only.. but if you don't want to get killed by the guards, then use alliance :P
