It depends on how much damage the party is taking. Healing is more adaptive to what is happening as opposed to using a set rotation. I am just mentioning the AoE heals you asked for in the first post, but let us know if you want one for single target as well.

If the damage is considered on the light side for the party, you can generally counter it with Assize + Afflatus Rapture, Afflatus Rapture x2, or a Medica 2.

If the damage is starting to hit moderately harder and / or more consistently, Asylum and Temperance start to get cycled in with the "light cooldowns". You preferably try to stagger these 2 rather than stacking the cooldowns so you can last a longer amount of time healing through the moment. These are also important cooldowns to use when the tank pulls really big for those 4 man Expert dungeons.

Then when it starts to get heavy, almost all of the tricks come out of the bag. The remaining cooldowns Thin Air and Plenary Indulgence start getting used with the multiple Medica / Cure 3 casts that are needed to keep up. The choice between Medica and Cure 3 depends how tightly stacked the party members are.

The cooldown Lucid Dreaming is always used on all 3 occasions too. Don't wait until you are out of mana though. Try to time Lucid Dreaming at around 80% of your max mana. You will want to make full use of it just like with Assize.
