Strange thing is also the casualty ratio. For example: I had a party composed of 7 Sword sis, 6 Swad knights, 11 Sharpshooters and 10 Sarges fight against a group of 16 Vaegir knights, 12 horsemen, and 12 veterans (plus me, marn and borcha, but they both were unde 30% health so the do not participate).
If I let the computer simulate the battle (eg. "Order your troops to attack while you're back). With a Tactics skill of 3 the game gave me an advantage of 2 iirc.
The battle ends always with many losses on my sides, usually at least 2-4 units (random, except for knights that seem to have less chances to die), 3-5 woundeds (or the opposite, more dead less wound), and equal or even less casualties on computer side: 3-4 deaths, 1 to 5 wounded.
Then I tried to simulate the battle, participating by myself, but without taking any role in it: no orders, I just went to the farthest map edge and dismounted, nobody chased me. Well, sometimes 1 or 2 swordsis or knights die or become unconscious, because they rush foe and became outnumbered, later 1 or 2 foot idiots (sarge or sharposhooter) are knocked out or killed. Foes die like flies instead, 10-20 of them are slaughtered, 1-3 knocked down and then the battle ends.
So simulated vs passive battle equals to:
-me: 5-10 out of combat vs 3-4
-computer: 5-10 out of combat vs 11-23.
The strange thing is: why if the troops are just the same, everything is the same, a simulated battle causes at least double the casualties of a played (passively) one? And more important: why does computer losses so many more fighters during a battle if I do not even participate?
