How about this as a solution, make the NM's Hunt mobs only targetable, poppable and get credit if you or some one in your party has the Mark sheet handed by Hunt Board. So that only those that have the weekly mark get credit and hunt it. I honestly thought this was how it was going to operate to begin with... but no its free rewards at all times, (not making it a weekly hunt but a farm hunt) people are just farming the hell out of it because they can. If they make it so that its an actual weekly hunt then the horde would disperse because reward has been achieved.

Plus the "fix" of rng weekly hunt mobs is horrid... I was expecting it to give each person a different weekly hunt, but everyone still gets the same weekly hunt mob, which causes the horde to just go after that mob and make it hard for anyone to get credit. The Marks should be RNG per player not per serverwide.
