Imo the the rewards for all the quest in this story line where to far and inbetween,honestly i was disappointed by ToAU 20 and stopped,i just level in the new area's and buy from the AH,i sell everything on the AH in jueno due to the tax on the AH is half the price than whitegate,i might do a besieged here and there but meh.......
Basiclly i have better things and drops to do/get.
