I thought Rough Rider America was in an alright place? Brazil is decently strong if you don't go overboard with chopping, they're just a vanilla civ that doesn't have any real pizzazz imo. Ottomans are one of the stronger domination civs, but I would like them to switch Suleiman's UU (Janissary) to be the civ's UU. I think Sweden is in ok position, Kristina is a bit disconnected from the CUA since she prioritizes GWAM but Sweden only provides a minor buff to getting scientists and engineers. Poland is a weird mix whose abilities don't mesh with each other imo. You lose a military card slot, discouraging you from going domination, but then you're supposed to build encampments and forts. I get that they wanted Poland to maybe be a semi-defensive religious civ but idk something feels off with them for me. Nerfing Korea at this point just means nerfing the Seowon since that's literally the only reason anyone plays as Korea. I'd be happy to see the Seowon toned down and the other three aspects of Korea buffed or re-worked, especially the CUA which depends entirely on the Seowon so really there isn't even a CUA for Korea.
