I didn't work on DoW2 but I worked on CoH. The core AI engine was similar. CoH added features to improve group pathfinding and pathfinding for when terrain changed, etc. I don't remember all of the details since this was 5 or 6 years ago. But the fundamental problem with AI is not building the AI. The problem is tuning the AI. You end up with a terribly tuned game if you give designers too many knobs or if your knobs look like a helicopter cockpit.
