[Mana]

Speaking of guns, regarding what I've mentioned before and haven't mentioned:

Pulse rifle: too strong rn, high pick rate for most players

Mp5: close 2nd to pulse rifle, can absolutely shred 
mid-close distance

M16: far as I know, it's a perfectly balanced gun, it's a curb stomper in far-mid but you can get fucked in a close encounter.

Sg552: last time you tried to buff it, it was a dangerous motherfucker, but with the massive inaccuracy nerf, it's not viable so not much players use it anymore.

Shotguns: seem to be fine to me.

Mp7: could use a minor accuracy buff, you wont see someone dedicated to it.

Vector also seems to be fucked to shit so no one actually uses it anymore, (I cant think of any potential buffs since I dont touch it anymore).

Other than that, I have no other input of the other guns as I have no experience using or dealing with.

Sorry if I repeated anything, just giving my input as of now.
