Huskarls hp and attack arent low theyre quite good; attack same as cavaliers etc, just the melee armour sucks
Battler, mangonels and onagers deal melee damage, so that infantry wouldn't work as intended.
like a huskarl? (except for the onager thing as pierce armor doesn't affect it
This is not how it works. Cataphracts have armor against anti-cavalry, not against cavalry. A unit cannot have armor against a specific unit type, just against an attack class.Battler, mangonels and onagers deal melee damage, so that infantry wouldn't work as intended.
