Small error in the above ^
B3 and F3 have a shorter CAST time in the opposite thing, but they have the same RECAST time as Fire 1 - BOTH rotations would have an additional 1.34s added on to them, which doesn't change TOO much, but it makes the 25s rotation much tighter and likely stops you from getting that F3 proc in with 5 F4s.
//edit: After testing it (with Sharpcast to force F3 proc and Convert to give proper Mana after said proc) I run out of Enochian during the 25s rotation consistently.
Rotation was:
Eno>B3>B4>F3>Sharpcast>F1>F4x3>F3P>Convert>F4x2>B3>B4 cast times out when Eno drops.
(Using Sharp before the B4 allowed me to pull it off at quite literally the last second - it's insanely rigid and requires 25s of completely uninterrupted casting)
