In Dragon Ball Super, we see that Beerus (God of Destruction) gets overpowered and knocked out easily by Whis (Angel) in a single blow.
Does it make sense that Whis, an Angel and attendant of Beerus, a God, is stronger than a God? Shouldn't a God be stronger than all of the Angels?
Furthermore, there is the Grand Priest who stands still yet above all the other Angels, and by extension, the Gods of Destruction and Creation?
