It took half of the surviving Amarotines to create Zodiark and make him stop the calamity. Which means that they were already used not only for creation but for actions. They told us that he had to rewrite reality to stop it too. But afterwards when the dust settled they noticed that the world was kinda death so they needed another half of the remaining ones to change that.

Hydealyn was seemingly only getting sacrifices from the ones that summoned her and if the rewritten reality just needed something there to control it, then I dont see a problem here. Her power is less but with sundering Zodiark she made that even. And since the laws and everything were already changed she may just have needed to take over the place without any more power at all.
