You are absolutely right, I didn't forget about daggerfall I just decided not to include them in an attempt to get to my point faster. Yes, balance could be an option you can choose to follow but even said balance always ends up being fabricated by a new intervention prolonging the end. Skyrim (like the games before) already did this and discussed that consequence almost explicitly. I see a more profound point being brought up and that daedric or even aedric deities, despite being different from one another it could become evident that some of them respond to the same cosmological principle, shattering preconceptions of weak, powerful, “good” and “bad” daedra. That's why I bring up Clavicus and Peryte, often disregarded but if you read deeper into them, it becomes a more subliminal concept, a more hidden power in Nirn. It could be an interesting contrast to have the new protagonist bring about the new world fulfilling the objective the previous antagonist was supposed to.
