Coming to understand WHM in endgame

[manamoppet]

Sad to hear lilies truly aren't used cause on paper the idea sounds great but after looking over exactly how it works I due see its flaws.

There was a lot of improvement on various issues in patch 4.5, but lilies probably won't be useful until the new expansion. We'll just have to see.

So if I am understanding everything correctly to sum up healing in general terms, and I'm talking super general, for example throw out Medica II, Regen on tank(refreshing both when needed) and then from there fill in time with DPS such as Aero II and Stone II (or stronger variants once I get them) and Holy then if tank is about to take full frontal damage from a tank buster be ready with a Cure II or III depending and making sure Asylum is out during extended fights?

Well, generally you don't use Medica II when fighting mobs outside boss-fights in the lvl. 60 dungeons and up, as it can affect the tank aggro more than regen, especially since most dungeons (that I can think of) have ambushes/ reinforcements. Cure III if more than one PC can be healed from it, otherwise Cure II. But that's the gist of it, yes
