Its really easy guys ...form a group with another toon then when you are in front of the door leading to bwl logout with the toon you want to use to do the instance .then while he is logged out get other toon to leave group ,log back in and you will be inside in front of the port to bwl.
Simple. You take off your gear and die in front of the closed gates. You die, go back inside, go through those doors and come to the room filled with some eggs. Log out there and log in. You will be revived and you can kill those Whelps there, when you kill idk how many of them in 15 seconds, you get the Jenkins title.
