Very informative post thanks.
Of course i did not refer to the technology of the Khuzait, it was merely when fighting against them, i think the other factions with huge economies like Vlandian and The Empire have no way to counter Khuzait, their high tier infantry and archers just doesn't do it. They are good though fighting other infantry, but against Khuzait they have nothing, Khuzait is pretty much strong on all fronts, specially mounted and from range and their spearmen is not half bad either, not to mention the Noble Son's troops like Quangli. Unit wise they are the strongest in the game overall.
