I know I shouldn't but ...

Importing the muster field from VI works quite well too. The comp will still build peasants, but they will be quite less common.

BTW does anyone know how to reduce the the comps fondness for ranged units, without putting in a big mod?
Lesser of these would improve the comp's army quite much as it cannot handle heavy ranged armies well.

If you are playing version 2.01 then you could load Medmod 3.14. It not only removes peasants but it re-prioritizes what the AI builds so that they tend to have much stronger armies (and not archer heavy either). They also trade really well so they have money for upgrades and infrastructure. If you do load medmod, try starting some games in high or late as the AI has even better troops.

Or, if you want something quicker, just try the link in my sig...

I didn't want to actually get rid of peasants, I just wanted to fight armies that had a larger variety of units.

I finally figured it out. I found a guide on adding a faction that has a blurb on faction behavior, which is what I was refering too. The guide was written by Starkhorn.

There is another sticky by Duke John about how to balance AI armies out. As soon as I figure out what he said I'll implement it. Thanks for all your help.
