troops' AI

SC it would be great if barbarian's, archers wizard etc were a little bit more intelligent... I mean i don't want them to be as smart as stephen hawking but more intelligent than a spoon would be great !!

Example :
If there is a hole in the wall in front of them -> they go into !!!!! If it's possible to enter the village then they must not go around the village like a bunch of cows.

Same thng for the king !

I'm fed up of doing more than 90% and get one stars whereas the walls were full of holes but my troops prefered to circle around...
