My pontus game has been quite successful but im usually utilising a hammer and anvil system in battle. Problem is i dont have great cavalry. I have the choice between Medium Eastern Cavalry, Cappodacian Cavalry and Hellenic Medium Cavalry but nothing heavier. Sure im not expecting cataphracts but is there something you can recommend?

btw, galatian heavy spearmen and pontic heavy infantry are really effective, use them on my flanks a bit. Recommend them for anyone who prefers a more fluid battle style
