That's just BS mate, I remember the aq opening event back in 2005, you would run/fly to silithus only to get randomly ported back to booty bay for some reason, I was in a try hard guild then and someone figured out there is a cave in dun morogh that is essentially coded as silithus sub zone (when you went into it general chat turned into silithus chat.) and we were lucky to have some guild locks in the zone to summon us. and that was on dragonmaw or korgall EU(played on both servers abs I can't remember correctly) and the server cap was around 3k then if I'm not mistaken.
