I don't know much about the med2 AI files but the "kamikaze general" which seems to be hardcoded in to medieval 2 is best solved with a workaround... by having a hidden bonus giving all AI generals extra hitpoints (in the traits file). It's the default in Broken Crescent and it's a very good idea.
I experiemented with 8 hit points but that was ridiculous they were like terminators however 5 hit points makes you think "oh crap the general is charging" rather than "I'm about to win once that idiot jumps on a spear" which is what any sheep worring arseweasel would think. But no... some of his bodygard may get faceplanted but he fights on usually with a few men for a minute or so. Long enough for support to arrive which it always does with this battle AI (and when the support arrives watch the general try to detatch himself, another feature of this BAI I see often).
The point is the generals don't drop like flies and in an interesting side-effect it appears to improve AI general survivability in the field in AI vs AI battles. Or to put in another way - there's fewer "captain armies" running around after a few decades than you normally see.
