At the start of an AoE run, if you have Convert, Swiftcast, and Raging Strikes up, shouldn't the rotation be:

F3 > F2 (until under 1000 mana) > Raging Strikes > Flare > Transpose > Swiftcast > Flare > Convert > Flare > Transpose

That way RS hits for all 3 Flares and Transpose is back up by the end of the 3rd Flare.
