Many people are saying that light brewing has the advatage over BoB that it gives the charges spread out over an even ammount of time but if you think about it, this isn't really the case.
While yes, Lightbrewing does grant slightly more frequent charges over a constant duration, you can do the exact same thing with BoB.
(the following numbers are made up but roughly correct)
If you use Light brewing you would probably start the fight with 3 charges, use one and then get a new one about every 8 seconds and spent one every 8 seconds, hovering at 2 charges most of the time.
With BoB you would start at 3, use ISBx3 and then pop BoB. Now you are at 3 charges and only generate one charge about every 9 seconds which seems like more time between brews. the thing is if you still spend one brewcharge about every 7.5 seconds (more often than in the light brewing example) then your brews will go down slowly BUT once they get down to about 1 brew left, BoB will be ready again. Then you use the last charge and pop BoB, starting the cycle anew.
So while BoB does seem like a bursty brew gain choice, you can play around this in a smart way to have the benefits of both worlds (more brews AND very smooth charges). Playing that way it completly obliterates Lightbrewing :/
