Lets take Type Otsu Rifle as an example… 420 rounds per minute
In what world can a human pull trigger on full rifle caliber 7 times per second?! (420 / 60)
This leads to stupid moments like this…
Your first shot does something and the rest turn into popcorn blanks and this itself is just stupid looking from gameplay perspective
My Proposal
Reduce Rate of Fire to 100-120RPM for Tier II (5 Mag) and Tier III (10 mag) Semi-Automatic rifles as a balance feature and remove the ultra extreme bullet dispersion (when firing at this rate) and bullet being a blank mechanic
Tier IV Semi-Automatic Rifles would get 160-180RPM along with other better stats such as accuracy.
Alternative Proposal
BR 1 Bolt Action Rifles → 18-24 RPM
BR 2 Bolt Action Rifles → 25-30 RPM
BR 2 Semi-Auto Rifles → 40-60RPM (5 Mag)
BR 3 Semi-Auto Rifles → 40-60RPM (10 Mag)
BR 3 Semi-Auto Rifles → 80-100RPM (5 Mag)
BR 4 Semi-Auto Rifles → 80-100RPM (10≤ mag)
Example
Type Hei / early (5 Mag) - BR 2 -----> 40-60 RPM
Type Hei / early (10 Mag) - BR 3 —> 40-60RPM
Type Ko (10 Mag) - BR 3 ---------------> 40-60RPM
Type Otsu (5 Mag) - BR 3 --------------> 80-100RPM
Type Hei / Late (10 Mag) - BR 4 ----> 80-100RPM
Type 4 Rifle (10 Mag) - BR 4 ----------> 80-100RPM
