In terms of Scout rifles one can buy from vendors, before the expansion, it used to be Aries Nemesis for me, because of the field scout & firefly perks. they're both very useful in raids. it's a lovely scene to see hordes of thralls explode. Now, my favorite is the Saterienne Rapier from the Crucible quartermaster, mainly for the Firefly perk. able to precision kills dramatically increase reload speed compensates for the low mag size of 13. other scout rifles are all fine. they just don't have very unique or hugely useful perks. and I'm yet to obtain the vision of confluence. here's my dream setup for a solar burn nightfall: vision of confluence, icebreaker, and hunger of crota. it's gonna be a piece of cake.
