I've hardly seen a suggestion to nerf Perm Weapons aside from the DC17S Spring weapon and the Christmas Sniper (which has been retuned 3ish times?)
I think maybe suggesting nerfs would result in more guns being nerfed.
There was a broad generalization a few months/years back (i can't remember) that just basically said... "redo all perm weapons" with little reason, ideas, or why. If there's specific weapons you feel overachieve, and the community agrees, something would be looked into.
I think the prevalent issue is people begging for weapon buffs, instead of asking to return weapons in the class. It just causes a constant damage boost or something similar that causes GMs to adjust for it which makes guns less unique in the future and more OP as we compete with previous weapon releases (kit or store).
At this point I think suggesting needs to weapons will be healthier than buffs or unique weapon variants, as nerfing these would allow GMs to low droid HP and bring PVP more in line.
