I still wonder what would have happened if the demons and angels had all stayed and fought.

Joker: "So, what's the status of the war?"
Deva: "Eos killed all the people fighting, so... There's not much going on."

If you consider a faction leader a raid boss, then Eos would have been overwhelmed with significant numbers like that. She DID pass out from exhausting herself in only a few attacks, after all, so dodging and stun locking her for a few minutes would have been all that was needed.

Or just don't get in that fight in the first place.
