Just off the top of my head:
-Universally, every primary headshot weapon has received a modified red-reticle range. The Light Rifle has been slightly increased, with the DMR’s lowered to match this new standard. The Battle Rifle and Carbine’s RRR has been lowered as well, identical to each other.
-Battle Rifle damage has been increased, the weapon now requires 11 bullets(4 bursts) as opposed to 13(5 bursts). Rate of fire has been slowed ever so slightly to compensate.
-Carbine received a spread reduction, along with a damage increase. The Carbine now takes 7 shots to kill. Rate of fire is unchanged.
-The Light Rifle received a rate of fire alteration for both scoped and unscoped shots. While scoped, the Light Rifle will fire much faster than before. The unscoped Light Rifle has the same shot delay as the newly-modified Battle Rifle while retaining the 14-bullet kill.
-Each automatic received a reduced autoaim angle. Your reticle must be centered on the target more than before the update. Bloom expansion has been slightly reduced on every loadout automatic weapon.
-Each automatic loadout weapon received a damage increase. Each one now takes 3 less shots to kill. The Assault Rifle now kills in 13, the Storm Rifle in 12, and the Suppressor in 11(unsure).
-The Storm Rifle’s ammo consumption has been altered. For every 2 shots, the battery will be reduced by 1%, granting 200 total bullets.
-The Magnum’s damage has been increased slightly. It is still a 6-shot kill, but the 4th bullet will leave just a sliver of shields left. Due to the Magnum’s lack of bleedthrough, the 5th shot will only take out this sliver, and leave the health untouched for the 6th bullet to kill with a headshot.
-The SAW has received a considerable damage increase to compensate for the new Assault Rifle. It now kills twice as fast as the Assault Rifle.
-Both the Mantis and Warthog chainguns have received a damage increase.
