I would like to keep Chu Ko Nu.
This is an entertainment piece anyway, and it is not undesirable to have something less accurate for the sake of entertainment. Although CKN has never been a commonly used weapon by the Chinese in the real world, it is a classic symbol of Chinese civilization in the AOE franchise since 1999. Since this game still belongs to AOE, it is not a problem for it to have CKN, or in other words, it should have CKN.
The three-eyed Gunner can still be used as a completely new unit rather than replacing the CKN. As long as we give Chinese civilization a way to access it, such as shipping it from HC, or even introducing potential Chinese Isolation options (replacing Germans in the Consulate) to offer it.
I know that solving the artillery problem of Asian civilizations is a good topic, but in my opinion it should not be like this, allowing players to train cannons that can be automatically upgraded in Castles with general resources and in a general way. Otherwise, this would amount to completely removing the intentional limitations to these civs and suddenly making Castle artillery their advantage. In other words, it not only harms the identity of civilization but also breaks the balance.
I came up with a similar concept, but still kept the core design that European cannons still have to be obtained through the consulate with exports.
I used to support this idea, but now I don’t think so anymore.
The banner armies are the identity of this civilization, but also its intentional limitations. Removing them is likely to make the civilization lose its characteristics and seriously affect the existing balance. I guess the devs wouldn’t want to do this.
Even assuming it were to be implemented, it would be an Age IV card rather than an Age III card, and it would likely be expensive. Also, after this card arrives, each unit will be at least 10% more expensive I guess.
If I were to do something with the banner armies, what I would prefer is to put the Age II banner armies in one type of building and the Age III banner armies in another.
