They tend to be obliterated when I charge with them too. Perhaps I should be playing with smaller units, but even my tough and hale generals take some serious losses before getting to the other side of an enemy unit with the unit size setting I am using.

I understand that chariots are not especially good in prolonged melee, but neither are cavalry and cavalry do not have the absolute lack of armour that Casse chariots have.
