Question about rebel AI

[dazr0b]

I've just rediscovered EBII with 2.2 and started a Campaign as Rome.
I was really impressed with the way the AI ran their army up the closest hill to gain an advantage when I was attacking and all was going well.
Then I made my move on Northern Italy and had a large army in the North with a stream of single units on route to re-enforce their numbers. On route to the front, a single unit of Triarii were attacked by a 1600 strong rebel army. I thought what the hell and instead of retreating thought I'd see how long they could last it out. Now I did use the pretty shady tactic of backing the Triarii into the corner of the battlefield, but my idea was to see how long they could last it out with a frontal assault while outnumbered nearly 30 - 1.

Then came the problem; The rebel army advance and then halted in front of my line and just continued to reform.
Now I understand that the AI will not try and attack full on if they are at a disadvantage and to start with thought this was them trying to lure me out of formation. (Very cunning I thought). The problem was that that was all they did until the end of the battle. Then because they lost the battle was "auto killed". So I was a little confused how 63 Triarii could destroy an army of 1600 men without even waving a spear.

A few battles later I came across a similar scenario. This time I had a reasonable sized army caught between to full stack rebel armies.
I set up in formation with the Principes in the front rank, Hastati at the rear and Triarii holding the flanks (Now I know this isn't the historical way of setting up, but I have found this a much better formation.) I basically then sat and waited for nearly 4,000 rebels to attack. Problem is they didn't and just danced around again in front of my lines until the end of the battle and because they lost were automatically destroyed again.

I've got to say I now feel a little cheated that I could experience the blood bath I was expecting.

I'm playing medium / medium.

Any suggestions how to make the AI More / Less intelligent would be greatly recieved.

Thanks.
