I'm not sure where this fits into a reply or if anybody's mentioned it but as far as remote-tempering goes
Lore-wise, Bahamut remote-tempered Nael and Midas through the coincidentally(?) named Lunar Transmitter in like 2012, so there's that, lol. I think we're just seeing what happens when an Ascian has all the toys and no interest in balanced, controlled escalation for a Calamity that requires hyperspecific conditions.
