I just logged in to my lvl 21 priest who was in the vicinity of the fire festival NPCs in SW. I walked to the area where the fire pit was yesterday and then started taking AOE fire damage. Then I died. This is useless as far as I can think unless you want to lure low level noobs into this area and watch them die.
The only thing I could think of would be to summon some people to that spot, but its possible that this might be useless. Interesting glitch nonetheless!!
