With proper use of archers, cav archers and cav it is entirely possible to lose no men in battle that weren't killed by your own archers. The AI is incapable of keeping any cohesion among it's companies and they separate and follow your archers all over the map. Once they are mostly killed by that archer fire it is easy to force a rout with a cav charge and then they are all dead. With an army of 300 I have killed 350 and lost not one single man. This is just plain silly! We need an AI that is at least as capable as MTW and preferably more so.
