I'll need to update the OP eventually
I'm trying to dupe my PS4 Hunter to my PC Hunter. That means fully upgraded all subclasses (I main the Nightstalker), getting the Stompies exotic boots as well as the full Optimacy armor set, and then a Scout/SMG/Merciless combo. Sitting at 12/124PL and Gunslinger unlocked. Once I hit Level 16, the Nightstalker artifact should be a guaranteed drop and then comes one of the longest grinds in the game.
BTW, highly recommend everybody saves 5 Blue or higher Scout Rifles. Trust me on that.
