There is a boat in Stranglethorn Vale up the Wild Shore, all of the three boats that belong to the Bloodsale Pirates you're able to run to a safe zone upon the ships if you're able to die from a multitude of mobs.
Follow these instructions:
Follow the arrows up to the top of the log, but as you reach the top of the plank, jump. Timing is essential, make sure you run and jump.
Simple as that, like the wheel in deadmines instance, they will now be unable to attack you.
