I tend to avoid using Scout Rifles, Pulse Rifles, and Sidearms in PvP. I typically run an Origin Story or Guiding Star for my Kinetic, Uriel's Gift or Stochastic Variable for my Energy, and either Sins of the Past or a sword for my Power Weapon. Main reason is that I find it easier to adjust my aim while laying down constant streams of shots rather than quickly and accurately place my shots, and I love the versatile moderate-long engagement distances of Auto Rifles when paired with an SMG or another Auto Rifle. It helps that I have Uriel's Gift and Stochastic Variable in all three elements depending on the challenge(s) I need to go for in a given day. I play my best, but I mostly just get my challenges done so I can get another roll at Shaxx (I really need more Better Devils so I can stop swapping it between my chars when I want to swap characters). As you might have guessed, I focus a LOT more on PvE and it's frustrating that one of the best PvE kinetic handcannons is both so random to get and locked entirely behind PvP turn-ins, matches, and weeklies.
