What about God Serena, he defeated the 4 Top Saint Wizards, on his own, the reason he lost was simple... IT WAS ACNOLOGIA!!!

In fact at least it makes sense for the Spriggans to lose:

Ajeel lost because he was arrogant and let his guard down. Dimmara lost because Sherria power was enhanced to its future potential, besides she was a God Slayer & Dimarra had a God Take Over spell, so it makes sense.
