seriously who came with the idea that grigoris can beat archangels. It is more than clear that archangels are stronger than grigoris because they are the highest type of angels.

I believe that archangels(or at least Michael and Lucifer ) can beat leviathans but I could be wrong( hopefully we get some information about that in season 11)
