Just a thread I thought I'd start, based on a lack of such a thing. The purpose is mainly to point out over/underpowered units, building, techs and the like.
To start off, I would like to mention that the Australian Native Police seem too powerful considering they cost one population.
Comparing them to similar units such as the Hussar or just the Anglophone Light Calvary, the cost to stat ratio seems reasonable as they are a little stronger for the extra cost. However, as a late-game unit when resource gathering isn't as much of an issue, the half population compared to most hand cavalry is incredibly strong.
