Refining WHM Tips

[Ersahi]

Does this sound like a good opener on a boss? -->Regen->Cleric Stance->Presence of Mind->9 Stone III's-> Aero->Fluid Aura->Assize->Shroud of Saints->Hi-Elixir->Cleric stance (off)->Divine Seal->Medica II (Usually AoE has just occurred)-> Regen->Asylum-> Then back too DD rotation?

I am no white mage master, but why no areo 2 or 3?
