After nerfing their bonuses, and nerf on eagles, nerf on monks and buff to longsword and gunpowder, they are kind of nerfed to the ground on the combined effects of all these changes.
I guess now stats site down today but they show lowest winrate of 45%. And they aren’t picked in open map tournanment anymore. Just sometimes picked in closed map occasionally and Yolo-style castle age full monk push.
They are mostly die to good cavarly civs in imp so they need to win early but even in early game before castle, lacking scout is drawback for long feudal age and their eco bonus only start to kick-in from late feudal-early castle age. Many cavarly/infantry civ already have sizable eco/military advantage there.
Some of their nerf should be reverted. I think getting back 18% faster military production would be start, which can improve their feudal age where they currently weak. Also need to buff Jaguar warrior more.
