I have the feeling the chu ko nu from the chinese civ are very weak compared to the other special units. I havent had the option to see all of them yet, but my friends play the japanese and the greeks, i believe, and their unique units have amazing extra stats, whereas the chu ko nu dont seem to be on that level at all. Not to mention the upgrades, 2 damage up per level?? I am still fairly new but it doesnt seem fair to me. On top of that, the said bonus of extra men from the town center? They are warriors even when you proceed over the ages? How does that even dent enemies late game? Maybe i am wrong, but i felt like sharing this.
