I still find the idea of Cataphracts replacing Horsemen very odd. They were in service throughout the entire middle-ages and only disappeared with the Byzantine Empire itself, if Cataphracts replace horseman than they should at least come with a anti-infantry bonus.
I'll just wait until we get an official confirmation on the Cataphracts being Horsemen.
