AF/AF0 = Job Quest Reward (first set)
AF1 = Allagan Tomestones of Mythology purchase (second set)
AF2 = Allagan Scrolls* (third set)

af2 wil most likely be on a new token style system

example: endgame content will at random reward group members upon completion (one per completion randomly to one group member - like house parts currently drop from HM and BC - a "scroll" or part of armor in token form, "Helm Scroll" would then be handed in to the npc in mor dhona for the helm of your choice)
