-Overall-
I almost exclusively use scout rifles as primary weapons. I used to use autorifles but never looked back after they nerfed them incredibly after the beta. Working on my pistol proficiency because I have a hawkmoon now, and Word of Crota is pretty fun in PvE. My staples are Badger CCL with firefly and Mida Multitool. Recently got Vision of Confluence and it works amazingly too.
As for secondaries, I used to use fusion rifles all the time, but those got nerfed too. Even with shotguns nerfed recently for range and damage falloff, I've actually started to use those almost exclusively now for PvP. Felwinter's Lie being my shotty of choice, Found Verdict on the side, Invective for PvE. I still love using Plan C, which I used all the way up until I got Felwinter's Lie durin last Iron Banner.
Heavy- I have Hunger of Crota for Raids, and several iterations each of Deviant Gravity A, Joldur's Hammer, and Against All Odds for PvP. I'm not really one for rockets most of the time, but my most wanted exotic is the Ghorn of course.
