Basically any Hive Major that can survive a Critical Hit before the Hive Bonus Damage kicks in the Precision Bonus Mag will NOT activate. When shooting at any Hive Major (Wizards, Knights, and Ogres (I can't imagine any Thralls and Acolytes surviving a hit)) will give you two sets of numbers. One set of numbers represent your Bullet Damage while the second set of numbers represents the Bonus Damage. The Bonus Damage counts as Non-Precision Damage thus countering the "Three Rapid Precision Shots" that the gun holds so dearly. Shooting at Hive Majors with three rapid Critical hits does a sort of "Critical, Non-Critical, Critical, Non-Critical, Critical, Non-Critical" hit set which as I'm sure many can that this can cause a slight... problem. I didn't say to much to the Oracle Disruptor perk with VoG weapons because they were doing what they were supposed to do without degrading the effectiveness of the weapon since they do the very same thing with the occasional Bonus Damage. Bungie simply copied this process over to the Hive Disruptor perk which hurts the effectiveness of the Black Hammer vs the Hive Majors. Simple fixes would be either make the Base Damage do more damage to Hive Majors percentage wise without the second set of numbers OR make it so that Non-Critical hits don't counter the Precision Mag Bonus when Critical are being made. Hopefully this gets addressed and fixed soon.
