Obviously the leviathan lore was not yet conceived by the writers during the apocalypse arc. You are also forgetting the leviathan follow their leader and their hunger. They could not have been used effectively for war not because of their lack of power but because of their inability to follow Heaven.

Lastly, "the whole species was scared. It's over, there's no argument at all." Quite the arrogance. Provide citations on leviathan being scared of archangels then maybe you can start claimig the argument is over.
