So seems this newest build has buffs outside of the aforementioned FrB and IL buffs.
Seems like AB had its average damage reduced from 2,090 to 1,849. To counter that, it had its cast time reduced by 0.3 seconds. So now it would take 10 seconds, assuming 0 haste, to get a full 4 stack up, unlike the previous 11.5 seconds. So we save 1.5 seconds while dealing 241 less damage. Unless I'm mistaken, that should end up being a slight buff in damage.Originally Posted by Blizzard Entertainment
The FO change is also nice.
