Kc also broke conservation of energy with incubi, would be impossible for the feedback loop of men feeding on monster mana for sustenance to occur.

I would say that men still need to eat for energy to be added overall, but the total amount of mana in the loop would decrease over time. They could sustain themselves off each others mana for a short time, but not indefinitely.
