I stance dance a lot in lvl 60 dungeons and this is how i run it:

Tank takes an endless number of mobs and pops aoe threat ability (Circle of Scorn or Unleash or Overpower)

On tank pop Divine seal + Regen -> Asylum -> Tetra on tank (if tank is at 50% at this point) -> Cleric Stance -> Prescence of Mind -> Aero 3 -> Holy until mobs are dead or tank needs more healz.

Single target is more or less the same but add Aero 2/Aero 1 at the step with aero 3 and trade Holy for Stone 3.

It seems to work pretty well for me in most occasions
