I broke down in anger and edited several Egyptian units. Elephants and Chariot archers are troublesome, but I think I have the most trouble with mass fielded units. I would personally rather go up against a unit of Elephants, one or two chariot archers anyday then go up against an army full of platemail Vikings, er.. I mean Desert Axemen. What ever happened to heat induced fatigue while in the desert and wearing heavy armour? Guess it was only an issue in 14th century and not BC. I just don't see exhaustion making any real effect on battles with the exception of movement.
