Im in a guild that really tries to start some world pvp on our server. We try so hard that when we invite low levels to the guild or mostly those who just start in hellfire peninsula, they usually comment that since they joined the chances a horde will attack them first has increased by 90% or so... My motto is: If its red, its dead! And the only time i dont follow this is if the horde are superior in numbers, or if its a) a warlock or b) a hunter with equal or superior gear. Another exception is if they are doing a hard/irritating quest, like escorting the skettis guy, wait time for him is forever.. BUT if i was attacked while escorting i usually stay in the area and kill everyone i see doing the quest =)
