I get where you're coming from, cav is pretty amazing as attested by our fine enemy in this game before he quit it before it ended. However, i have found more often than not that the issue in itself isn't the horses but exactly how often you get a clear spear into the head of the horses on your screen and then it just continues on while the enemy couches you right down, i always play spearmen so it happens quite often, this was just a one off all cav match for me and a few friends.
