Both of those prayers mention some sort of intercession and ultimately request responses from God Himself, so they don't prove your point:

St Michael: "by the power of God"; St Mary: "implore your intercession".

"Hail Mary, full of grace, the Lord is with you. Blessed art though among women and blessed is the fruit of your womb, Jesus. Holy Mary, mother of God, pray for us sinners now and at the hour of our death. Amen."

Asking Michael to defend us, not asking him to do something by the power of God as later in the prayer. - “Saint Michael the Archangel, defend us in battle.

Asking MARY for an answer to the prayer. - O Mother of the Word Incarnate, despise not my petitions, but in thy mercy hear and answer me, Amen. “

Despise not my petitions? Why on earth would someone think that Mary would despise their petitions anyway? What kind of Mother of God is she?
