I have shared many ideas for the consulate before.
If this mean to make the skins of consulate artillery be like Mysorean Rockets that be operated by locals, it is fine.
The problem is that allies don’t offer different things for different Asian civilizations. And the names of their units are those units’ Royal Guard names. I respect the game’s design in that regard. I can interpret it as based on friendly and close diplomatic relations, Emperor Kangxi and Emperor Akbar invited Britain to send troops to help him fight the enemy. As the same, Tokugawa invited Netherlands to send troops to help him fight the enemy.
Now the Dutch can train them. Just saying.
Why not reserve the Dutch and add the US?
Chinese Isolation would be a good option to replace the German ally.
China Isolation makes sense to lower the cost of banner armies and provide many new Chinese units.
The units there may be like:
Three-Eyed Gunner
A new ranged heavy infantry with a three-eyed gun, firing in bursts of three shots like Chu Ko Nu. Has shorter range than Musketeer and better HP than Arquebusier. Trainable in groups of 5 at Consulate from Age II.
Langxian Spearman
A new hand heavy infantry with a langxian spear. Has low speed, and quite good attack multipliers against cavalry and heavy infantry. Trainable in groups of 3 at Consulate from Age II.
Glaive Cavalry
A new heavy cavalry with a classic Chinese glaive polearm like guandao. Very tanky with decent melee attack, but slow. Trainable at Consulate from Age III.
Manchu
No longer a mercenary. A bit weaker than the original one but still powerful. Trainable at Consulate from Age III.
Jingal
A new ranged infantry with a type of large matchlock gun carried by two soldiers, having a higher attack and longer range than Arquebusier, pretty good against heavy infantry and buildings. Trainable at Consulate from Age III. (The place of button is same as Consulate Artillery and Meiji Restoration, since it’s somehow similar to abus gunners but more like an artillery).
In fact, the units of Japanese Isolation and Chinese Isolation should be regarded as their unique consulate units without regular versions, rather than the consulate version of an existing regular unit. Even if it’s the consulate version of a regular unit, it shouldn’t be a mercenary. For example, Hatamoto is supposed to be either a brand new samurai-type unit with consulate unit status, or the consulate version of the regular samurai, but not the consulate version of the ronin mercenaries.
As for the Ottoman allies of the Indians, it would be more accurate if they could be replaced by the Persian allies in the future.
