You left out indep. str, but I quess you have it quite high. Try advancing more carefully, or playing with fewer enemies. And as especially Ulm and Jotunheim have much better provincial defence than is usual, you should learn to use it. However, don't buy it everywhere. Having 1 is enough vs AI if it cannot reach it with normal armies, because AI rarely uses transport or distant summon spells with any real skill.
