Using them in PvE is so underwhelming, expecially into Activities where enemies are more resilient. Even with Perks like Rampage or Kill Clip and a Minor Spec Mod it takes so long to kill Red Bar minions. Orange and Yellow Bar enemies requires magazines on magazines to get killed. I think that the only Auto Rifle that Is worthy to use right now is the Breakneck with a Rampage Mod from Ada-1. There are so many cool Scout Rifles in the game right now (Oxygen SR3 first!) taking dust into the Vaults 'cos there is absolutely no reason to use them. Hope to see a good Buff for them with Shadowkeep.
