In my games, the Cataphract and Dromon usually outclass the Legion and Ballista for coastal raiding. Since the Cataphract can fortify and has three movement, I think that makes up for the -2 combat strength compared to the legion. Also, the Dromon doesn't need to set up to fire. I don't know if this argument has been made before, but I think the Byzantine makes a better early warmonger.
