Do you think the devs intended multi-flare blm?

[Pacifyer]

Or just maybe try... flare (regular fast cast from being in rotation), (save a fire 3 proc) convert - swiftcast - flare - transpose, wait for a tick or two of mana and use the fire 3 proc and try to fast cast your 3rd flare. Then pop your best ether and go right into bliz 3.

You can't get your Fire 3 proc cause you do not use Fire 1 in AOE situation. All you do is Fire3 -> 3x Fire2 -> Flare -> Convert -> Swiftcast -> Flare
Again, if you are using Fire1 somewhere is is definitely a dps loss and you are doing something wrong.
And doing this in single target rotation I can't see much use of it cause it is a very small dps gain and can occur very rarely due to aether pot cd.
