Yes, but we know they are Hunters, constantly training and improving. Roman has no formal combat education, much less is receiving one constantly like them.

They are expected to develop their Semblances, since they are constantly training all their skills. Roman is not, and hasn't gone to a Hunter school of any sort, so he is not expected to have a Semblance yet.
