Why do you not think it is practical. The RTW AI is dumber than a chicken. I own about 110 territories as the Romani by now and it takes me about an hour or even more just to do everything on the strat map, but by Jupiter, is it worth it! I never let the AI do anything in any of my Total War games. There is just nothing that you could do to make the AI do things better except taking over yourself. Not only this, but I enjoy all of that micromanaging more than battles actually.
