Maybe I could have played the original better, but I played a mage on hard and higher magic was essential. As a warrior on normal in AP I find that stone skin, healing, resurrection, dispel, and trap are the only spells I use (I haven't found phantom yet ; pain mirror is very rarely useful; and mana ball is better than calm rage). Avenging Angel simply costs too much mana and stone skin is better than the one that refund mana when your tank gets attacked.
