The ultimate goal of the Exalted combat Charms should be to force all combat to occur on the scale of human combat; i.e., resolvable by individual heroic human action and the movements of armies. It should basically no sell anything above that. The Exalted Host wasn’t stronger than the Primordials by any objective measure of “capable of wrecking shit”, they were merely capable of forcing the Primordials to fight them on the Exalted’s terms.
Which, it turned out, the Primordials were not well prepared to do.
Then, one escaped and did come back respecced for that level of conflict and almost overthrew the entire Exalted host at the height of their power.
