Purely imo, but I think we could nerf the RoF to 100 ms from 97 ms, and increase the damage to 13 from 12.
This would only change SO much with the gun, 26 damage on headshot from 24 means you’ll kill certain mercs in one less shot than the Crotzni, and the slower RoF would mean the gun wouldn’t bloom as fast and maintains good accuracy while spraying.
To compare damage, here
24 48 72 96 120 144 168
26 52 78 104 130 156 182
So you get a slower dps with the SMG 9, but you get more damage per shot. I’d calculate DPS but I’m not sure how you folks get your numbers to be honest. :\
