First, I don't know who decides on weapon balance. Before it was little orbit themselves (ray casting for shotguns, improved rifling percantage range) now they do what SPCT tell them to do or I don't know. They make VERY strange decisions like: let's make PMG useless and buff OCA. Let's make NFAS useless and not allow it to be used in fight club. Let's destroy cherub pistol because a couple guys were using the combo with CSG / JG in fight club. Let's destroy PIG + Perc because it's so easy to pull off (have you actually seen more than 1% of players doing that)?
Here are my suggestions:
Revert PMG, OCA, PIG, Perc to pre-OCA fire rate nerf
Revert OBIR nerf
Fix or revert the N-HVR damage nerf when not fully zoomed
Revert ATAC nerfs
I think Manic was overnerfed, haven't seen a single person playing it
Add back ray-casting to shotguns, maybe increase shotgun range (improved rifling is mandatory on shotguns right now), also maybe increase shotgun damage
Increasing STAR's fire rate could be a good idea
Decrease Obeya CR762's damage from 245 to 235 / 230 / 225 and/or reduce the range from 55m to 50m
Stabba CCG: increase stamina damage to make it 7 shots to stun or increase fire rate and/or increase magazine capacity from 20 to 25 or 30
VBR 'Huntress': 2 open mod slots instead of 1 and/or decrease maximum bloom
Carbine and n-tec 5 are in a good spot right now
I actually liked little orbit's changes don't know why they went back on them or why people didn't like them
