Update, he got a DoH up to 56, Mogloo still has nothing for him. Another friend (who's on a trial account, even) managed to get Mogloo's quests.

Things we've eliminated:
* DoW/DoM too low (he tried a L63 job)
* DoH too low
* Didn't finish A Nutty Initiation (he has it in his Completed list)
* Need to have beast quests open in general (he has rank 3 with a couple of the ARR tribes and Neutral with the others).
* Kupo Nuts (not even a serious proposal)
* Insufficient MSQ progress (he's at "enter the Aetherochemical Complex" like the rest of the group)

All that seems to be left is that there's another side quest that none of the online guides and wikis have noticed is a requirement. I wish the OP on this thread had actually DETAILED their solution six years ago.
