I think your making it difficult I think you take a special journey with Tolland and you go on this massive story line to corrupt the Matador with the darkness like thorn. Now here is the twist you find out its already been corrupted so Tolland hands you duct tape and you strap year 1 thorn to the bottom of it and when you pull the trigger it shoots both and you use up & down on dpad to change if you want single fire, 3 round burst, or full auto but you gain intrinsic perks shot package, range finder, rifle barrel, final round (every round). It is now upgraded to exotic which you can equip a second exotic while this can be placed in either primary or secondary and regens ammo every 5 seconds. But this might be a nerf so idk.....
