FINALLY got to rank 50 with FWC last night and got the catalyst for Sunshot. I played for about an hour afterwards using Sunshot only and got to only 9% of the "Sunburst Kills." Holy shit that's going to take some serious grinding...you really have to find groups of adds who are very close and very weak to get those types of kills. Either way I still love Sunshot and it's fun to have both Firefly and Explosive Rounds at the same time. I also finally got around to doing some of those Curse of Osiris "Heroic Adventures" for the powerful engram and got my first Forge Weapon... it was the scout rifle and I absolutely love it! It feels really good and reminds me of the Cocytus from D1. I'm pretty burned out after grinding for Rank 50 though...I did it all solo so that takes some extra time. I'm still not sure why the faction vendors give out anything besides faction gear though... kind of shitty to get 2 full sets of non-faction gear before a full set of faction gear.
