Are you all blind or what, he's not chaining bolts (notice how the cast bar disapears for a GCD?), he's dumping 1 FoF IL at a time only he's not prioritizing dumping all of his Ice Lances on the crystal bc he probably wants to fish for 2 BF FFB, as said earlier, BFFFB imputs more damage than IL+Cleave by a whole 100% SP, and he utilizes both (as well as both INs) on the last 4 seconds of the crystal.
This reminds me the video of Blood Legion world first Protector of the endless where the PoV dps attacked the wrong target for a whole minute. World first guys.
Wait, so i should prio FFB procs on prismatic crystal in opener? FFB > IL > IN to dump procs?
40k butcher? They are more like 30-33k
No, the real answer is much more complicated.
At the end of PC you should FoF-IL>BF-FFB.
At the beginning of PC you should just minimize proc munching (which might mean prioritizing IL over FFB).
FoF-IL > BF-FFB at the end (when only the first spell will hit PC) can be easily verified by checking total damage done.
I'd also argue to prio this a little earlier to allow all stored icicles to cleave.
Either way the general question is very difficult to answer entirely as there are many sub cases. I also didn't check where IN fits into this (certainly higher than BF-FFB, but not sure about FoF-IL because of stored icicles), but again it depends where you are in the duration of PC, how much stored damage you have, and how many charges of IN you have.
No one ranks #1 consistently on anything relevant without having it handed to them or playing a spec no one plays. #1 is either RNG or maximum padding with some RNG to top it off too.

That would imply that they are not able to practice that much either and since I doubt there are 'plenty' of players out there that could just waltz into these guilds and perform out of nowhere that makes this statement bogus.
