Some interesting numbers on 4.0 BLM

[StouterTaru]

Transposing is normally a dps loss. You have on average one second and a half of 0 pps

Foul takes less MP than B3 in AF3, so Transpose > Foul doesn't require any wait.

Rotation time -1.0 total:

• -2.5 for no B3
• +0.5 for Transpose
• +1.0 for F3

Potency -120 total:

• -168 from B3
• +48 from F3 under UI1 instead of UI3

You need to sacrifice a F4 to use a TC proc on 4.0. You simply don't have enough AF time to use TC on 4.0

Transpose is a dps gain in the B4 rotation, and allows for use of thundercloud procs:
2x F4 > TC > F1 > 4x F4 > transpose or
3x F4 > F1 > TC and 3x F4 in whatever order > transpose
