The most swift and heartless dose of karma I ever got was in that death knight city don’t ask me how to spell it and someone fell off the edge to their death, I had a sudden urge to be a dick in that moment and flew down to their corpse to /laugh when then rezed. They seemed to find it funny too, though. (We were horde and alliance so couldn’t talk). After I had my fun I mounted up and flew off but accidently clicked one of my abilities that caused me to dismount and I fell to my death.

I think every DK has ‘fallen’ off of Acherus at least once.
