Recently Black Ops 3 has been updated with some weapon tuning.

Little bit confused why some of the tuning was done against some obvious balances issues. Studio is using various bits of data to make choices collecting player feedback have some faith given current meta. Treyarch has done decent job overall but issues between classes in my mind.  What do I know end of the day not very much only have small minor opinion.

Light on real numbers again but that normal for most studios.

Given some information which can be found here Weapon tuning

Normal sources should have the real numbers within couple of days/weeks.
