Dear Healers who don't DPS

[Starflake]

Regen + Asylum on Tank -> Swiftcast + Holy -> Enemies are stunned -> Thin Air + Holy spam -> Tetra/Assize when needed.
With the almost constant stunn Holy gives the HoTs have enough time to heal the tank and the huge damage kills the mobs super fast.

This and don't forget that Benediction is a great thing to use as well. When you're as comfortable healing as I am, it becomes a natural thing. Let tank dip low and use Benidiction if I don't have Tetra. It's a three minute cooldown and seems like such a waste to not use it. You can use it up to 5 times in a good dungeon run.
