What WOULD be nice, if you ask me, is if Levi HM, Ramuh HM, Gilgamesh, chimera, hydra, Cape westwind, and Shiva HM actually dropped something.
Anything. Crafting materials, a minion, barding, a friggin SANDWICH.
Just give us something to look forward to other than a paltry amount of tomes. Maybe have things with no loot table provide more Light for the nexus upgrade.
