I've been trying to reenact the battle for minas tirith but it's kinda hard. First of all the ai never seems to use battering rams or siege towers, they just blow holes in the walls and leave all the other siege equipment behind and mass charge through these two little holes in the wall. And this is hard difficulty I'm talking about here.
Is there some sort of trick to make them use siege equipment? Other then taking away their catapults and ballistas I mean.

Also one other question, is there a collection of historical battles that I can download that use the new settlements? That would be great.

cheers


P.S. I'm more a custom battle guy then a campaign guy, I almost never touch the campaign in Total War games.
