just go into export_buildings and change the recrutment pool from 5 4 to like 3 1 or something, go into export_units and change the knights hitpoints from 1 to 2 or 3. u can also lower the number of knights from 60 to 20. I totaly agree that you the armies should be mostly comprised of militia and sergeants, with less cavalry and knights. By changing the recrutement pool to 3 1, that would allow only 1 knight per (specific building). so if u have 2 castles with a barracks in each, you can now only have 2 dismounted feudal knights across your entire army.
ps. i also love when your city has no cavalry and spear/town militia as defence. When the enimy attacks with 10 units cavalry, couple militia and the rest are knights.
