I understand your points (pun intended), but honestly, in a grand strategic game where units are large (such as armies in this one, and to a lesser extent, corps), and operate over a large area, the generalization of point-to-point is perfectly fine. To me, anyway.
I don't want all my games to be like that, but I enjoy it as a different approach to wargaming grand campaigns. The only other point-to-point game I have that I can think of offhand is Eastern Front Solitaire by Omega Games.
