I see that some problems still exist with the AI, and some of them are of the fun breaking kind. On Rome TW I could easily deploy a single stack of any heavy or light cavalry in front of a hostile enemy wich didn't possess more than 1 stack of the same and win the fight by luring them into persuing me (wich happens only when the odds START against you) and then I just drove them into exhaustation taking their cavalry first and then their infantry units one by one. The same is still true for MTW 2, the AI is more agressive on the Battle Map and on the Strategic Map, but that doesn't make it so much better when there's a clear problem of design.

This is what happened:
1- I start a new campaing on VH/M with France.
2- I build every comercial building possible and recruit every cavalry unit possible.
3- Move my agents to their respective possitions and recruit a merchant.
4- I take four separate cavalry units and order them to siege four different settlements (Dijon, Bordeaux, Metz, Rennes). Yes that's right only one stack for each one, even when two of them have a healthy stack of mailed knights.
5- Set all cities on very high tax level and pass the turn.
6- England offers me trade rights and map information in return. I ask for money.
7- Is the turn of the rebels. Everyone decides to attack my lonely stacks and one by one, as described in the strategy above I take on them and defeat them. No sweat.
8- My turn again, only one turn passed and I already have 4 more settlements with almost no loss (or at least not regreatable loss).

How cool is that!!
