Really unlogical tech tree and AI

[Abokasee]

When I say unlogical, its because of something like this:

Castle: Woohoo I can get Druzhinas!!! but whats this I cant dismount them? isnt this simply a act of get your backside of a 4 legged mammel name a horse?
Mustering Hall: No its not, you have to upgrade me to the top level
Castle: Ummm, why? do you have some superb device able to dismount my men at a rate of 10 men a second?
Mustering Hall: Maybe...
Castle: WTF!?!?!?!?!?!!? W0OT IS THIS MADNESS!??
Mustering Hall: Madness? this is MTW2!!!!!!, all the other factions have to do this, like are neighbour, Poland
Polish Castle: Hey look at me! I can spam with my Barracks Dismounted noble AND mounted ones!
Castle: Arghh...
Polish Castle: Im gonna declare war on you, just too show how many Of these little ******** I have, and then can replace the next turn

*114 turn war*

Castle: Jesus christ that was alot of Polish nobles,
Barracks: Yeah, surely they cant just suddenly turn peasents into Nobles that quick
Castle: Yeah its suprising how many russian Vikings live in russia, especially smolesnk (Off topic, theres a point, what happend to Vikings for russia, they were in for MTW)
Barracks: Well now im at top level, and so is the Army barracks in novogrod and moscow, but not kiev because the poles kept massacring the population, and we kept sacking it to get enough money to make more good troops, which brought the population to about... 751,
Army Barracks: Hey since we got these barracks, lets go steam roll hungary
Castle: Why not?
----

My point is, its quite easy too tell a man to get off his horse and fight on foot, especially if your king, also the AI has no sense of intelligence, and wont cancle its moves once orderd (like russia taking kiev, then besieged by a small hungarian army)
