I've 2 level 50's already, so I've unlocked all of them up to what was relevant in 2.0.

100k per duty roulette? That's remarkable. My Duty Roulette completion is giving me 4k. Which is a pebble drop in the vast ocean that is 180k exp to level (I'm level 32). I only get good exp once per day with the duty roulette.

Done Hunting Logs and Challenge Logs. Though even completing the whole rank 4 of my hunters log doesn't give me 1 level.

Atma FATEs, huh. Where are those situated in? I'm guessing not in the old, big FATE areas anymore, since they are desolate. 'Ill have to try doing the high level dungeons for my level.
