Im pretty sure the current aoe rotation is this

bliz 3, thunder 4, bliz 4, flare, flare, convert, flare, transpose, bliz 3, bliz 4, fire 3, fire 2 repeating

I find its an aoe loss to use flare without convert up and thunder 4 is a must for aoe rotation now as a proc is SOOO strong for aoe damage.

This rotation could be wrong but its what i currently use.
