I love this mod, it's something I've wanted for a while now. However I noticed a bug that only occurs when I have this mod active that maybe you could fix.
Barb outposts (almost always) are empty without a defending spearman. They still spawn units, but there's just no fortified defender, making clearing them trivially easy. I say almost never because I have encountered a few outposts with defenders. My guess (not tested) is that barb outposts that spawn later in the game spawn correctly with a defender, but those that spawn at the beginning of the game (or before players have researched some key tech) lack the spearman. Also, I didn't notice this bug right away because there doesn't seem to be any issue when the Barb Clans mode is active, only when playing with vanilla barbs.
Anyway, hope you can find a solution to this bug, because I love this adjustment. As for now, I'll just use it when I plan to play with the Barb Clans gamemode.

Thanks SilverFG,
