I pulled this one from Reddit and it's the rotation I generally use for aoe.

Freeze(Sharpcast)>T4>Foul(when available)>F3(T4 proc&Triplecast)>Flare>Flare(Manafont)>Flare(Swiftcast & Ether)>Flare>repeat. Not needing to transpose after flares anymore just keeps the dps flowing so much smoother now. Note you can be as low as 800MP* and still Flare.
