The devs should also release winrates, matchup-specific and map-specific. After all they seem to be taking this into consideration (straight up nerf Lakota and India due to winrate). However this shouldn’t be the only thing to look at when deciding balance. Reworking poor design like the Inca Age 2 rush which killed your TC, or the overpowered torps and Caroleans after all their upgrades are send also need to be adjusted. Inca was already adjusted, but we’re still waiting on nerfs/ reworks for Sweden. All Sweden players need to do is spam Caroleans, Anti-Infantry Artillery like Falconetts/Heavy cannons and Culverins. No other civ can get by with such an easy to micro and simple unit composition.
And Aztec and China need to be looked at aswell. Flamethrower need changes urgently, that unit basically doesn’t exist in 95% of the games. And China sees almost no play at high level because Japan and India are so much stronger. A small buff is in order so that China can compete with the other 2 Asian civs in 1v1. Aztec still has their terrible Skull Knights and Jaguar Knigths which need urgent changes, and so does Aztec as a whole. Its still a worse version of Inca in many aspects.
