it would be good to make a formation (like spear wall but different) for elite infantry to create more mass like deeper ranks sort of like a phalanx, im watching a history channel on the phalanx and the spartan equipment and troops were so heavy when in their formation they could be hit by a full frontal charge and not move an inch because of their weight of mass. how effective is your calvalry when thrown against a rock wall? and i forget who made the comment but i agree with the swords being better against horsemen in a pitched melee, gladius should be easy to wield when you just raise your shield to the horsemen and hack at his poor mounts legs.
