Dismounted mailed knights should have 10+ morale.
Aragonese knights should have 20+ morale.
DMK will break, under normal conditions, with 70% of unit decimated.
AK will fight to the last man.
Reasons: Aragonese knights are a superior unit to regular mailed knights.
Balancing need: northern european factions which can recruit mailed knights can also recruit a number of other specialty feudal units. Conversely, Aragon is limited to recruiting javelin units and weak aor spearmen, until later when Andalusian Spearmen (quality spear) are later available. Thus, their knights make up for it by being relatively unbreakable - the weaker support units responsible for harrassment via projectiles are generally easy to break
Historical need: Aragonese knights kicked ass
THANK YOU FOR CARING THOUGH!
