Farming in a zone and get jumped by a retarded rogue when mining a node - he laugh and kills you again when you respawn, just because he can. He might even spit and /sit on your face
I remember the joy, when spotting that f*cker later on and killing him on sight (because you could actually remember nicknames) and camping him until he escape. I also remember the embarrassment, when trying to kill him (even got the opener) and failed.
Revenge was a lot of fun - can't wait.
