Basically what I want is all the units in BKB's mod! That would be perfect. Especially Champion Swordsmen. Wow, they were so cool. 16 of them could butcher an army of over a thousand medium spearmen. Anyway, I want:
Skutatoi to give the Byz good spearmen
Cheaper feudal knights
Flemish mercenaries (in the early period for the Western Kingdoms, these should be able to be recruited 24/7, not just when some happen to be passing in the region). They were the staple of many kingdoms in the 1100s.
No obselence (if it isn't broke, why fix it?)
