Haha, I know his army revolves around cataphracts but they are impossible to catch and kill by nearly all cavalry without infantry support. And if you wildly chase after them, you get shot up by the shadowing horse archers. With the removal of ap from the kopis, the list of cavalry that can actually defeat cataphracts 1v1 in melee is probably only 2 or 3 anyway.

The other issue here is that cataphracts don't tire as fast as they should nor move as slowly as they should but that is not easily correctable, or in the case of tiring, hardcoded.

The other problem with HA as they currently stand is a weight of numbers issue. The 73 man and 66 man units create some issues because in a giant cavalry swarm, they outnumber anything civilized factions can hope to bring to bear and often can rout opposing cavalry simply through the weight of numbers morale penalty. In my battle with Arjos, you may notice that my generals BG turns to countercharge an incoming mass HA charge of probably 300-400 cavalry men and even though only about 6-7 of the bodyguards die in the charge, they rout even standing immediately in front of my infantry. I don't think the numbers should be changed, but this only adds to the current issue.
