For aoe fights its still f2 spam(mix in flares when you can).

Just to correct this - Flare is your main source of AoE damage. It's not "mix in Flare when you can" it's "build your AoE rotation around casting Flare".

To expand, the way you should /always/ do AoE is:

F3 > F2 > F2 > F2 > Flare > Transpose > [wait 1s] > F3 > F2 > F2 > Flare > repeat from Transpose.

If you have Max-Ether and/or Convert ready and you wanna use them, you can do up to 3 Flares back-to-back.
I'll also almost always Swiftcast my second or third Flare in the normal rotation to speed up the damage.
With Enochian, you pop it after your F3 at the start and just let it fall off in AoE situations. This is the same at 50 and 60.
