Given how small patch of land is left, I'll just prefer to leave the Uruks before they formed their full Silk Road style culture. So there'd be less helpers. Probably nomads and sand people ("barbarians") and dwarves found at the mountains who would like to hit up a good trade. Anyways, I think the main source of confusion is probably that you judge them on what Greenskins in WHFB are. These orcs are less of that crazy bunch and if I can say closer to Elder Scrolls interpretation of Orcs. I am actually considering to make them a different race altogether.
