I think it would be accurate if the Romans automatically threw thier pila as you charged them at an enemy, and would throw them automatically when standing to recieve a charge. I thought that is what they were trained to do - throw thier light and heavy pila as they go in.

I don't recall seeing any references to them 'skirmishing' in front of the enemy and then charging, which is what you have to do at the moment to get them to behave like Romans.

Would this be really difficult to implement in the code?
