FIs are already insanely good and this will just mean build Jans than do all the pops from various shipments and church techs. No need to train much. How does one kill 40 Nizams, 5 Great Bombards?
Ottomans actually need to not get any buffs atm. A few things need to be nerfed, I made some suggestions in this thread: https://forums.ageofempires.com/t/ottoman-s-historic-weaknesses-have-all-been-removed/248447
Ashis don’t need a buff.
USA doesn’t need any buffs. They might not need any nerfs, but they differently don’t need any buffs and these would be unbelievable huge.
Seems unnecessary. Why a random nerf to WWs?
Why? I hardly even seen this used.
Portugal could probably use something for treaty or extreme late game, I don’t think this is it.
What? Lets not do more random stuff that makes everything needlessly complicated…
This seems like a good idea.
No. If you can’t protect it that’s your problem. Let’s not have Japan rebuilding their Shogunate.
A lot of things in this list in general felt like “changes for the sake of changes” without having a clear reason for doing so. You suggested random buffs and nerfs with little justification, and a few of the larger buffs were for civs with the least need of them. USA is either fine or needs some nerfs, and Ottoman could definitely use some nerf (I don’t see enough USA to properly gauge their balance, but they are definitely pretty strong.). Overall, a lot of the things seemed needlessly complicated, and I don’t think we need more of that in the current civs. In general, I think it’s best to explain “x is a problem for a, b, c, reasons, I believe doing y will fix it”. That way a more substantive discussion can be had.
These would be great though.
