Both the current FWC scout rifle and hand cannon can roll with firefly+outlaw. Currently the PvE meta is mostly scouts and hand cannons. Autorifles and pulse rifles currently don't really do enough damage for taking out end-game PvE enemies. The god roll PvE rolls on hand cannons is the Fatebringer roll, and IMO it's best in scouts too, for the same reasons. Maybe TripleTap/Firefly is better on scouts, but FWC rolls that too! Suckit DO/NM
