DensterNY, what you're suggesting wouldn't work outside historical or setpiece battles. Time Commanders can program the AI to emulate the historical tactics because they only have to do so for particular battles, whereas in RTW proper the AI has to be able to cope with an in theory unlimited number of battle scenarios due to varying terrain and army compositions. The best that can be done is allowing the AI to recognize which units are vulnerable to certain other units, and when to commit reserves or attempt to flank with cavalry, but it remains a complex job to get a computer to be flexible or recognize and utilise the necessary tactics.
