I love the Scythians, and was quite happy that you added them in in the Persian Wars, but I was a bit disapointed by them. Three units? And the fact they were just copied from another faction's banner was a bit sad.
Not really complaining just saying. So I just let them be trainable in the normal campaigns (in those two provinces they control in the Wars Campaign).
I was wondering if the Scyths had heavy cav at this era, or did you just not want to bother adding in new units (I wouldn't blame you if you just didn't feel like it).
