For me the most important thing is AI must learn the difference of Armored divisions, infantries and Garrisons.I want to see AI use garrisons and infantries for beach defenses and armored and motorized divisions for stratejic reserves and if 15 INF take a province, AI should send it's reserves and if 15 ARM/MOT take a province AI should counterattack quickly if this counterattack fails, AI should abandon the line and make a new line.
