In Imperial Age Gujaras Elite Genitours have a lot more going for them they get +40% bonus damage meaning they deal 15 damage to Arbalest and 17.8 to Cavalry archers and with 75 Hp and 1.49 speed, and Kshatriyas I think they are a powerful unit maybe even over-powered.
You are also granting your berber ally +25% faster Camel riders and Camel Archers.
