Units routing in all directions more realistic. Really?
If I had just marched from relative safety to the battlefield I think I'd run back to relative safety!
Ok units running away from attackers fair enough but they should then attempt to get back home.
Also cavalry tiring as fast as they do is not realistic. Mongol cavalry was renowned for its speed and mobility, heavy cavalry charges were feared by most infantry. Slowing cav so they can be chased down by infantry is poor, horses can perform greater feats for longer than infantry. Why should cav tire by doing the very work they were employed for? What about fresh remounts? As many as 3 or 4 per rider with the Mongol armies. Light cav becoming fatigued by chasing down fleeing infantry is plain useless. Let's not forget the part that cavalry played in mediaeval warfare
