This thread is a good example of how there is two kind of people on MMOs : those for who the reward is the journey in itself, and those who do it only for the carrot they get at the end XD

Anyway with the amount of players complaining of fedex quests, especially the ARR ones, i dont see why you would want to get xp from NG+. Just do something else (roulettes, palace of the dead, etc), because if you dont care about the story you sure dont want to risk again to burn out and quit the game skipping too much dialogs and cutscenes as fast as possible, whishing to end that at the soonest. And i suppose SE dont want to lose players like that as well.
