I've always wondered why people complained about cavalry in SS. I've found that if you bring sufficient spearmen to battle and set them in schiltrons with a bit of space between each schiltron, cavalry will get massacred. This tactic is even more effective when backed by missile units. The only complaint that I believe has any validity is the Athanatoi (Roman bodyguard). However, that problem is even easier to fix. All you have to do is go into the edu and lessen the number of bodyguards in a bodyguard unit for each faction. If anyone else has figured out other solutions post them here so others can try them.
