I think the satavahanas could use a nerf. Maybe flipping less on their spawn. As it is now they tend to dominate india, and often persia and central asia for the entirety of the game. Egypt also tends to over expand, or over conquer rather. Maybe if the barbarians in the sahara were more willing to attack egypt they would have more to deal with and stick to their historical areas. You might also want to make Rome more likely to declare war on them. Rome starts off doing a good job of conquering it's empire, but usually stops at Jerusalem.
