Most classes have mind numbing AOE after 4 mobs.

Its not as simple as scatter for 3 mobs. Its:

3 Mobs: Scatter and alternate between VerAero and VerThunder to quickly build Black and white mana.

4 Mobs: Spam Scatter.

I like to alternate between using Embolden for one pull and Manafiction for the next.

Moulinet is what you spend your black and white mana on for a pay off on 3+ pulls. Your goal, when you plan on using manafiction is to get mana to:

15, 30, 45 or 75.

15 + manafiction = 1 Moulinet
30 + manafiction = 2 Moulinet
45 + manafiction = 3 Moulinet
75 + Manafiction = 4 Moulinet (use 1 then manafiction)

You also have all your OGCDS to weave, fleche, contre, Corps, Displacement, mana shift the healer, etc.

Sure its not SUPER complex, but its no worse than doom spiking, Holy spam, Overpower spam.
