I have no problem about fixing an "exploits". But now the Duncan run is now just dumb
The quest allow you to group with people who haven't complete all the bosses but won't let you know who is missing a boss. I have made the run 3 times today with people who claimed they have done all bosses but not.
At least let us know who is the fcuk wit is in the party who is wasting everyone time. Can Anet put a NPC in Umbral Grove that let the party know they have completed all the quest requirement for Duncan before they leave town. It take ages to find the right team then only to find you can't get in because some1 don't know the changes or just fcuk in the head.
