With the recent nerf to Fire2 and the addition of the Umbral Hearts mechanic enabling you to cast back-to-back flares, I've come up with a table for PPS. Please do note that this is my first time number-crunching so if you spot any errors please let me know!
This table assumes that you are not utilizing swift/triple, a spellspeed of 1276, and you have only 3 targets. I also included the old rotation for reference.

Will try to compute for anything beyond 3 targets soon. :)
