Hey, I think that now that Volatists can no longer be emboldened, Harbingers have a bit more of a role to play. Using them to horrify defenders, to speed up melee units feels good. But for that you only need like 1-4 Harbingers. Mass harbingers are kind of shit, even in towers their range is low. But a single Harbinger does a LOT of damage, especially when horrified. Overall Volatists benefit too well from being horrified. Therefore I recommend NOT using fire sconces or anything that removes horrify unless it's a farming/non combat area.
