I love this mod, it allowed me (as Seleukeia) to restore the rebelled Baktrian satrapy (ie make it a protectorate). I don't consider it an abuse, since I'd won every battle against the Baktrians and taken three of their cities, including Baktra. So they were down to three provinces, one of which my spy caused to rebel and another which was ungarrisoned and on the brink of revolt, and I had an army ready to hit their capital in 1 turns time. I figured that under those circumstances they should be begging for peace.
