Nice to see some progress, though I want to put my two cents here about shotguns...
The majority of shooters that I've seen that balance shotguns by TTK, tend to fall flat in one of two ways: The shotguns suck, or the shotguns are overpowered.
The one way I've seen shotguns behave in a balanced manner is treating them not as TTK weapons, but as the kings of popping corners, focusing on STK rather than TTK.
Since it seems poking at the shotguns has become the norm, I just want to put that little bit of an opinion out there!
Keep up the hard work, guys!
P.S. Just got down to the bottom, I believe you may have it backwards when it comes to the PMG and the OCA.
Both weapons can kill about 4 people in a magazine, but due to needing less shots to kill, I think the PMG/5 Shot Kill SMG is more forgiving than the OCA/8 Shot Kill SMG.
I don't want to seem overly opinionated, but it sounds like you guys are on the path to making the PMG a tad... broken.
Basing it on magazine size is all well and good, but if you count bodies per magazine rather than the straight comparison of 21 vs 30, the PMG is a tad more forgiving in more ways than one.
Heck, arguably, the OCA gets closer to a 5th kill before the magazine runs dry than the PMG does, at 3/4ths of the way(6 Bullets) vs 1/5th of the way (1 Bullet).
Sorry for being a ranting nerd, lol.
