U know most of these players only afk farm when they go to bed or go to work or something. Most of those guys know the game good enough to know how to use it in their adventage. They play the game more than enough, but probably do the farming for the materials when they CAN'T play. And they probably know farming nightmare hunts gives it faster, but they probably just wan't to play the game itself when they get online and get the materials without doing anything at all.
