First of all, great job on the new maps and natives. They look extremely interesting and I’m sure there’s a lot of love and effort put into them.
Now I think there is a problem very similar to the “older” civs: the “older” minor civs now look inconsistently underwhelming and uninteresting.
Most African natives give ~5 technologies. Many of them also provide two unit types or even a new hero. Older minor natives typically only have 3 technologies and 1 unit. I do believe they can be made a little more interesting and worthwhile, such as getting a few new technologies and units. Also some of the new features not present in vanilla can also be added to them. For example, Nootka war chief can be made a hero unit like the new African ones.
And that’s probably not going to have a huge impact on balancing and the current meta because native trading posts are still very underused.
Now that the announced DLCs have all be released, I really hope there are future plans to polish the existing contents of the game as well.
