I say this as a console player, PC players have like infinite recoil control or something so take this with a grain of salt
SMG- need viability at slightly (and I mean slightly for all you haters out there) longer ranges so it competes with shotguns at close range
High and Low RoF Auto Rifles- Kinda just meh in everything
Fusion Rifles (Excluding thousand voices and telesto)- anyone actually use these in PVE? They are fine in PvP
Sniper Rifles- Should at least take away full shield or full health (1/2 of total health) if you land a headshot with high impact sniper on a super. With how much flinch they get, headshots should be rewarding (Console players especially)
I mean smgs do. I use em alot.
Snipers I feel maybe a flinch reduction would be nice. Otherwise I think you're trying to use a high rof sniper. Ahigh impact sniper will either take them to near death or outright kill them in their super if they are low enough.
