All this really boils down to is the real PvPers are tired of getting lumped in with the gankers and the PvErs trying to quest are not making distinction. All I know is Panopticus and a bunch of his guildies ran an instance like pros and roflstomped the rude folks. It's an event that might be recurring but won't last forever, so sure, kill one or two people from the enemy team, but if you just camp all the quest zones, not actually needing anything there? Well, you're kind of a bag of feminine hygiene products.
Love you Animosity! =D
