There have been a lot of posts popping up explaining how the 3.0 rotation, F4>F4>F1>F4>F4, is better though. I suggest you use the 3.0 rotation for now until we find out what 4.05 will bring to the table for BLMs.
Umbral Hearts are available as soon as you get level 58, and Fire IV can be performed 6 times, similar to our old opener.

How our 3.0 rotation can somehow be "better" is beyond me.
