Some quick issues I noticed:
Korean Crossbowmen cost 30, though they should cost 36 like the Chinese Crossbowmen. (Both are Average Protected Crossbows)
Korean Bowmen cost 30, though they should cost 42 like the Chinese Archers (Both are Average Protected Bows)
Korean Light Archers should cost 30 instead of 24.
Their descriptions should also be changed.
The Korean foot POA seem to be affected by the number of men in the unit. I'm not sure if it'll decrease as they take casualties. Based on the description, the ones with defensive spear received their full 100 on impact, along with the 30 Heavy Weapon POA. Haven't tested to see if either of these oddities have gameplay effect.
Japanese Archers cost the same as Sparabara Foot, despite lacking their Light Spear impact.
Don't know why, but the Crossbowmen in the French and Norman list are supersized.
The new banners will be pretty cool. It'll be exciting to see the more detailed versions that'll show up in the Medieval version.
