There's been some talk that the new patch notes have nerfed grens and buffed penals and etc.
However, in line with relic's reasoning for changing small arms:
DPS values MOVED VERY SLIGHTLY (less than .5%)
Example:
Kar98k:
Prepatch: 3.8 near / 2.42 mid / 1.03 far
Post patch: 3.78 near / 2.40 mid / 1.03 far
Penal SVT:
Prepatch: 5.73 near / 3.62 mid / 1.50 far
Post patch: 5.78 near / 3.61 mid / 1.50 far
They did the math to get the numbers to work out to be the same. Why they changed grenadiers from 20 to 16 when it wasn't overkilling units is unknown, but their dps is still unchanged and they still do more dps than conscripts. Penals will no longer overkill units which may be a usability buff but their overall dps remains consistent.
Thanks for that Endeav. I'm pretty surprised they didn't tweak the Mosin Nagants as cons just feel so unimpressive right now, but I guess with the MG-42 changes and support weapon changes they need to be careful.
