In regards to the whole "Do I turn GB off":

I cleaned up my math a bit, and included ADII as well as incorporated AA's properly.


AA Pot (Did 35 non crit slugs, took out AD II and averaged them and came up with 4.05 PPD. Then took the average of my non-crit AA's and turned it into Potency) = 86



4x Split - 140x4
2x Slug - 180x2
1x Clean 200

17.5 Second (6 AAs)

560 + 360+ 200

1120 Potency

86*6

516 Potency


With GB + HS + ADII

(((1120 * 1.2) * 1.3) * 1.05) - 1834.5


Without GB

((1120*1.2) * 1.05)+ (516 * 1.05) = 1952.8



That is around a 118 Potency difference or 479 Damage over the course of 17.5 seconds which is around 27 DPS difference.

Taking off GB while fishing for Procs is definitely ideal. The problem comes in with Tunnel Visioning and knowing when to turn it back on.

Also for reference you lose around 37 Potency when you fire off Blank/Head Graze while out of GB.
