Black Mage Sanctuary - A Guide to DPS

[Thela]

But these changes buffs both 3.x and 4.0 rotation equally, so while nice they are adding buffs, unless there are other changes they didn't document it won't really change the status quo.

Add Foul to both UI cycles and that becomes 152 VS 149 pps, favouring the 3.X one. If the base MP buff (and the no MP Foul) allow for the 3.X rotation to get one more Fire IV, then the 3.X rotation yields around 155 pps.

But foul is on a static timer as long as you manage to keep Enochian active, so you will cast the same amount of them in the 3.x or 4.0 rotations. The timing on when you cast them may change, but ultimately you will cast the same amount of them in both rotations, thus you shouldn't really include foul in any calculations comparing the 2. The recast time of F4 won't change the amount you are able to cast either, only how fast you can burn through your mp, and you were already able to cast 5xF4 in the 3.x rotation before your mp dips too low, that's not gonna change.
