Funeral Crashers

Well, my friend linked me to this story, basically a person who plays WoW a lot dies, and her friends decide to have a memorial service for her in-game. So a rival guild decided it'd be funny to crash the funeral and kill everyone there. Now, to me this isn't funny in the slightest bit, however, I could understand if the deceased was really into PvP and the guild that crashed the funeral were big rivals (friendly rivalry) and they had a fight at the service. I mean, I think it would be cool to go out with one last battle in my honor, but going in with the sole intent to deface something that actually matters a lot to some people... Low.
