So long as the PT knows its a SR the tank should be running out in front. As a healer they should be following close behind and ready to Divine Seal + Swiftcast + Cure II > Regen while the DD's catch up and start burning down the group. A better healer can even after getting the Tank back up get a SS popped off > Cleric Stance > PoM > Holy spam > Shroud > Cleric Off > DS > SC > Cure II.

Its all in the group and rotations though....the Tank always plays the same way, if the AOE DPS is low...then the healer has to adapt and can't heal the same way.
