healing always comes first. if the tank pulls 10-14 adds you probably should not dps at all. i feel most comfortable with 6-7 adds. with only 3 i feel aoeing is a waste of my mana but without the stunlock from holy stance dancing is a pain. 10-14 are too much, even with holy's stunlock the tank will get too much damage. but i feel comfortable to heal through 14 adds ^^

i have a simple rule: if i have something to heal: i will heal. if i have free time: i will dps.

and with 14 adds there IS something to heal.
