I decided to finally re-roll my pre-DLC version of Felwinter's Lie, and this is what I got;
[b]Solar Damage[/b]
[b]Linear Compensator[/b] [i](Highest range increase of the 3 options I got.)[/i]
[b]Who's Next?[/b] [i](A kill with the final round in the magazine increases reload speed.)[/i]
[b]Field Scout[/b] [i](Maximum ammo capacity. 7 round magazine/21 rounds in reserve.)[/i]
[b]Rangefinder[/b] [i](Increase range when aiming-down-sights.)[/i]
I got 3 of the essential perks I needed; Who's Next, Field Scout, and Rangefinder. Only way I think I could do better is with Accurized Ballistics and Shot Package in place of Rangefinder; but I'm running low on Weapon Parts, and the odds of getting a 100% perfect roll are a bit too slim for me to consider risking it.
Still, I'm thinking this should help me fend off Matador and Party Crasher n00bs until the upcoming Shotgun nerf in the 2.0 Title Update.
It's a good roll but as u said wont be as crazy as shot package and aggressive ballistics, Matador is better if they have shot package and aggressive but you'll be fine
