The Patch messed up the difficulty settings!

Slaists,

Isn't that simply because the peasants in the hand of the human rout quicker at the higher difficulty level due to higher kill rate?

It is a morale slider now. I do not see any indication of an outright attack bonus for the AI anymore. When I tested this a week or so ago based on somebody's post I had very odd results. The interesting test was triarii vs. triarii. I seemed to get a better charge in (despite trying to match the AI's as best I could) and would win handily on VH. I saw some similar things with cav, but even with a winning advantage during melee my cav would usually rout early. So I think they scrapped the attack bonus for a morale bonus. That bonus is not always enough for the AI to win and is very sensitive to initial losses.

Easy battles take a lot longer. Probably because of increased morale improving defense in some fashion.
