I imagine somewhere along the way from 6.1 to 6.5 they will explore what it all means for us that the Blessing of Light might not be a thing anymore.

At the same time, I wonder how impactful the Blessing of Light has been anyways. It was more relevant during ARR and HW, though mostly protecting us from Ultima once and stopping Ascians from going at the Scions... And even without the Blessing of Light, we still have the Echo and the WoL being more or less an Ascian through the stuff with being the sundered Azem, we have other sources of plot power.
