While the big boy on the block is still out of town, I figured I'd take a shot at making a weapon re-balance.

Basic Design Overview

in general:
smaller magazine = more max ammo
damage by caliber

Shotguns mostly hit 80+ damage, balanced by ammo count and damage vs firerate
.32 and 9mm Pistols - 40 dam - 150 bullets
.40SW Pistols - 60 damage - 90 bullets
.45ACP Pistols - 80 damage - 60 bullets
Heavy Pistols - Pierce shields, plenty of damage, low ammo

SMGs are similar to pistols

Carbines - 40 dam - more ammo, less accuracy
Assault Rifles - 40 damage - 180 or 150 ammo, depending on accuracy and stability
Battle Rifles - pierce shields - 80 damage and 80 bullets or 120 damage and 60 bullets
 -G3 has DMR kit that makes it like the WA2000
 
Sniper rifles
.308 - 200 dam - ammo based on fire rate
mosin - 300 damage
r93 - 360 damage

LMGs are mostly the same.
Medium Machine Guns pierce shields, smaller ammo pools and ammo pickup
M134 is better, (pierces shields)

.50 Beowulf and 7.62x54R conversion kits (DMR kits) (pierces shields)
VSS stock for the As-Val is VSS + SP6 conversion kit (pierces shields)

Most weapon attachments have been rebalanced so there are multiple valid options.
60 rnd mags lose a small amount of total ammo.
Tac mags give +4 stability or a little extra ammo.

The m95, and the other special weapons are not changed.
Ammo types are unchanged (i suppose I could change things if someone wants me to)

Thanks to /u/Naviaux for the shield penetration code and DMC for making DMCWO, which i picked though to find all the variables that I needed.

I mostly made this for myself, but here it is. Please give me feedback for any bugs or poor balance you notice.
I'll make a version two shortly if i find anything that needs more balancing.

Unzip and drop the folder A_Squared Rebalance into your mods folder. This is a regular BLT mod.
