I made my own little modifications a few months ago... I gave every unit in the game +10 defence skill, because defence skill doesn't affect missle units, and i gave them all +10 morale as well, except for missle units who i gave only +5 defence skill and morale... Battles were awesome... Each unit would slog it out for at least 3 minutes before routing, provided they weren't flanked or something and battles lasted an enjoyable amount of time... This was in Barbarian Invasion... I also removed some units i didn't like like ballista chariots and monks... I wanted to give some units the "bonus versus cavalry" ability, like the all but pointless Roman Limitanei unit, but i could never get it to work.
