Yeah, dungeons are great exp/hr if you start at the beginning of the level range. As you level, the returns drop dramatically, such that if you can find a tight FATE cycle, it should provide better exp/hr. However, the original FATE cycle near Quarrymill was nerfed severely as well, so I'm not sure exactly how much you can get. You can run a multiple-camp FATE cycle, i.e. Tranquil+Quarrymill+Costa del Sol+Little Ala Mihgo, but only if you really want to burn gil.
