I got this idea after reading the 'Named Mob Wiki" thread in the general section of the forums.
I could easily see 6 or more quests from this idea:
Quests 1-6...the named mobs for each tier, probably given by the associated trophy hunter, and either an emblem or some unique attuned item when the quest is completed.
Additional quests could be for special mobs, such as Daknor, Fafnir, etc, others for a group of WD, or ED, or Satyr Island mobs...heck even one for each type of Vexator, or others for a certain quantity of a particular mob, example 10 or 20 of every type of blight in the land.
There are lots of possibilities here I think...not only a chance for quests for every level of adventurer, but a chance to have people to a bit more exploring and get unique items...attuned on reciept from quests that can't be repeated. then everyone has a chance and it's not something that can be camped.
Just an idea that popped in my head, which obviously still needs soem refinement, but could definately generate some activitiy and interest among both old and new players.
