I think that we only can farm then end part of rakkis crossing by using waypoint portal from home then teleport back to town before leave game. However, there have so many paths which may stuck you. Possible delay your farming time. This may also lower down your GPH if your bot stuck at there. I was found some location that DB should not go near, such like the door. When the bot walk through the door, it will stuck in front there. If DB successfully unstuck itself, it will continue to stuck at the stairs again, then go to center part, DB may also stuck again at the corridor.
