At any rate, I have no issues with destroying enemy forces using light or medium cavalry, though I mostly charge from behind with those sorts of units. People have even complained about cavalry's OP nature in the past, as well(especially when using hammer+anvil tactics). Fighting Steppe armies totally composed of cavalry in the open field without sufficient supporting cavalry of your own can be scary man.
I'm quite experienced with the Saka cataphracts. Let me tell you, I didn't kill just 5-6 men per charge when fighting baktria in the open field. I massacred them and broke their morale--but this was mostly after I had harassed them with my HAs though.
