I played as Haven, and I don't have any particular questions about it; everything is clear. As for the unit roster:
+It's good that there are no weak units with pitchforks and various elementals. I liked the Priestesses.
-They changed everyone's level again, and I have to get used to it all over again.
Comments:
1. The regular cavalry looks like an upgrade, while the noble cavalry looks like a regular unit. It would be better to change the color scheme so that it's closer to the old parts. (although then you'd have to change it for others as well, since almost all upgrades are blue. although the Priestesses' upgrade is white for some reason. either make them all the same color, or don't adhere to a color scheme at all, because it's 50/50, and in the end, you get confused with these upgrades during the game)
2. Why give the Incas female names if you can't really see it in the model? Just for the sake of it?
