As a healer, is it my job to DPS? A new perspective.

[Feyona]

Then yell at your tank or co-healer because something is amiss here. Either the tank has horrendous cooldown management or your co-healer decided to let you solo heal. Even before echo, A9 simply doesn't do enough damage to warrant the need for spamming. I suppose if your group were still ilvl 250-260? Still, the tank shouldn't be taking that much damage. I'm assuming they were in DPS stance. If not... wow.

Edit: Another factor is what spells you were casting. As noted, Succor wouldn't be the best option.

combinations of adlo physic and lustrate. Yeah tank low geared but he took almost a milion damage if I remember correct actually it may have been over a mill I was 250 i lvl at the time
