And Sairaorg's peerage were a part of DxD, so they were getting much needed combat experience. Just because the king happens to be the most powerful person of his peerage doesn't mean he's the only powerful one. I know we haven't seen them in action since Volume 10 but they train and are getting combat experience like the other peerages of the Rookie Four.
