I would maybe increase the defense flavor for Siam by 1? I think everything else looks good there.
Theodora Naval I would only raise to 6, imo
Darius gold and culture flavors look fine at the base amounts, far as I can tell? 8 is plenty
How about this for klepht?
Philhellenism - +1

Influence and +5

Gold for all allied/friendly city states on ranged attack (no benefits for being on defense)
I really like the
Yeast of Liberty (1.5x resistance CS bonus). Is that possible to work in? It would give Klepht a comeback mechanic, which is really useful for such a late UU, and gives them a unique ability that can't be countered by an enemy player CS-hunting
@Hinin, I haven't ever really seen fit to acknowledge or commiserate with your illness. It didn't feel right to comment on your condition when I'm just a lowly pineapple on the internet. I hope your health continues to hold up, and I am glad to hear that this project continues to be a source of strength and excitement.
I look forward to continuing our work together, and a happy new year to you, and everyone.
