The 'without sense' of AOE-3 that should be corrected

I had this idea for giving bulls to a few civs:

I’ve also seen a suggestion for some native allies having a passive bonus such as enabling or increasing the build limit of livestock. So a Quechua ally could allow you to make some Llamas, a Navajo ally could increase the sheep build limit, or an African ally could enable some cows.

How about just flipping the role of Keshigs and Manchu? Keshigs seem more like an elite guard that would be more suited to be a mercenary.

A tech for the Explorer to train them instead would be better. I’d like the second unit from the Tengri shrine to be the Mongol Scout, but with the added bonus of having a falcon ability like the AoE4 Khan.
