i would consider heal for mage even in higher maps just to have as an instant way to get back to 100% hp even at the cost of lower damage , since it can save your life in situations when pots aren't fast enough . If your war makes a mistake and a bunch of mobs start attacking you , heal and then use maxed out gale to get far away from the fight thus reseting the agro back to the war ( point gale backwards or your extra screwed XD )


i would use shield , gale , fire , heal , with heal being used only when everything is already focused on you and you have nothing to loose .
