Stances?

[Anadorn]

<p>While reading the updates to the mystics once NDA was released it was mentioned that Mystics have a DPS stance and a Heal stance so I've logged on checked my spells, checked my abilities, checked my personae cause just maybe it was a click a check mark by chance (was getting desperate) and found nothing checked to see if it was an AA I had to unlock and found nothing in there but the second tier says it depends on if we are in our "healing stance".  So....just where are these stances and how do I select one over the other...</p><p>Very confused mystic</p>

<p>Disregard, found em although I didn't expect them to be the final two abilities unlocked in the new tree thought they were just a new element to the class.</p>
