Hi, I just saw the video! Great work, both of you.
Call me superficial, but what intrigues me the most is the rotation, namely which ranks of LB you choose to use. It seems like we have two givens:
We can't spam max rank lightning bolt the entire fight because it's inefficient, especially when we have procs and item effects at our disposal
We can't spam rank 1 LB to fish for procs or kill time between item effects because that's not efficient either.
Therefore the sweet spot is somewhere in between these two extremes.
For the "bad gear" situation, you go with "R9 LB until your fourth cast without a EF proc, then cast R8s until EF procs. (Then CL when EF procs)" What was your rationale for settling on the magic number of 4? Did you calculate some kind of probability curve, which could extrapolate into, for example "3 casts of R8, then 2 casts of R7, one cast of R6", etc., if an EF proc never occurs?
I'm not a statistician, so I only have a feeling that there must be some divine mathematic behind this. I don't know -- did you go that far, or did you settle on when (and how far) to downrank based on gut feeling? I would love to know.
