Since I think you have a point, please explain it for me and for others better I don't understand it as of now.

We are still on farmed content right?

Short summary of what I do:
Tank runs in with stoneskin, I pop divine seal -> wait for initial initial hate gain (most of the time flash), tank gets regen, I'm on the GCD -> time to activate cleric stance, time to DPS

-> if the mobs are not dead by the point regen wears of: toggle cleric stance off, Cure II, regen, toggle cleric stance on -> DPS

-> last mob on the brink of death: stoneskin, toggle cleric stance off, start at top.

Where am I supposed to use stoneskin?
