Well, I'm horrible at the modding, very slow and I get distracted easily. Mabye we can make a list of units that:
a. Are fine as they are (Romans)
b. Ok, but need a few touches. (I think the Greeks, right?)
c. Very sad, but salvagable if need be. These need to be totally reskinned (aka all shirtless barbarians, the pajama Parthians, etc)
d. These units must be taken out, and everyone must forget that they ever existed (Screaming women, breast cup Amazons, etc.)
e. New units that should be added.
