Based off my observation and some advise from thousands-hours old players, here are some weapons I would like to see a change on it:
BR16/Stark: Quicker burst, and less spread, make it feels like back in the old days but not that op. Anyway, burst rifles deserve better stats since they take some skills to handle.
(You can turn Stark back to the lazer burst but only have a magazine size of 21 rounds and slower reloading, since the weapon model has a smaller magazine)
Dreiss: A bit less spread is all it need.
Grandeur: Buff RPM to around 240.
SHAR: Buff RPM to around 500 and nerf magzine to 25.
Ahnuhld: Buff RPM to 120 or increase effective range, since Fletcher and Rhino ususally cant deal the maximum damage outta it due to their mobility.
MK46: Buff damage to 12, nerf magazine size to 75.
K121: Less overall recoil, less zoom in when aiming, nerf magazine size to 50.
Tomahawk: HITBOOOOOOX!!!
