The price difference is basically the same between a Rouncey and a Courser, yet the Cataphract is significantly worse of an improvement then the difference between any other tier of a horse. Buff Cata HP, lower Warhorse HP, and take a look at the maneuver values. If anything, they should be lowered across the board for heavier cav. Also take a look at the armor increase especially, 3k between War Horse and Large War horse for 3 more armor, 9k for 4 more armor between Large Warhorse and Cataphract. It just doesn't seem right to me. The next horse, Charger, has 11 more armor for about 8k. The Cataphract needs a slight buff and Large Warhorse slight nerfs.
