calyth said:AI didn't really pick a choice other than running a max function and picking the hardest hitting unit it has on its stack. And this type of combat has already existed in Civ 3. Basically the combat system picks the strongest defender for the attacker.
There is no good alternative to make a tactical choice on who's defending aganist what unit.
A warrior probably couldn't even land a blow on a knight. the knight has a 10:1 odds of killling the warrior, and I would be surprised if the warrior would even take down one strength of that knight. Not allowing you to choose the defender would definitely speed up a MP game where both plaers would try very hard to outsmart each other in choosing which units to attack. I haven't seen how useful is the 2 first strikes in combat to comment whether keeping the samurai would be a good decision.
There is a combat breakdown around here somewhere.. I can't find it right now, but basically... it says first strike is VERY powerful.... especially since it saps the enemy's strength before they start fighting. 2 landed samauri first strikes could make a mace man useless, and leave the samuari almost unscratched, without a too generous RNG roll.
