Chu-Ko-Nus have a much lower ranged combat strength than crossbowmen, and they cannot benefit from the logistics promotion.
Normally, I get 4 archers with logistics in any game on Epic or Marathon. Not getting Logistics as the 4th promotion is a bad idea even as China since it doubles the effectiveness and EXP gain rate of archers. Logistics Archers promoted to Chu-Ko-Nus are worse than normal crossbowmen.
Chu-Ko-Nus would be useful if you use catapults or don't fight classical era wars. But who does that?
