I'd say kudos to you for finding this out. Hell, I might try it myself. Even I took my solo Pally to Booty Bay and kept killing the Horde's Flight master on Pirate day tryin to get people to flag and brawl. Before then I brought my Rogue down there, barely 70 at the time and /sapped those that were flagged to tempt them. I got a few, but seeing the Booty Bay guards coming to my aid. Sat on top by the Captain and watched each person that attacked me get launched off the roof. Ah, what fun. And yes, I'm on a PvE server myself.
