I play Dominions 3 essentialy in Solo Game. I can imagine my "avatar" - the pretender - leading armies, speaking with commanders, or strolling between people.
In my vision of Pangaea, I see minotaurs, centaurs, satyrs, dryads, males and females fight together against the civilised world.
Females units doesn't have any gameplay purpose, it's only for diversity, for the story (this female centaur are spouse of this hierophant, this female pandemoniac is in fact the mother of hero taurotyrannos, etc...).
To have little differences (-1 att, +1 def) between the two sex is a good idea.
But -2 to berserk rating ? mmmmh, I don't know. maenads or female minotaur must be very... Aggressive
I don't find the holy commander who was not sacred. Do you have the id ? The mod runs properly at my computer (only this mod, dom 3.10).
PS (edit) : I don't test the mod with AI leading Pangaea.
