Absolutely right, I also use a few big armies to defend my territories and to attack. When you have a short border to the enemy with only two to three territories that border on the AI's territories you can also build two to three armies and conquer the whole AI territory in a few turns. It can't react to massed attacks, so it's always easy to defeat. Often it retreats its troops from border territories so that you can effortlessly conquer them. The AI needs some changes in overall strategy to have more chances against human players. Its action often seem pretty random and mostly aren't reactions against actions by human players. It also still tends to attack neutral or enemy territories with forces that aren't fit for the job. Saw it attack a neutral territory four times until it managed to conquer it in the last game, and it lost a few times against only a fighter and one AWACS unit.
