Thorn is a great PvP gun in my opinion so no need to buff it there but here is an idea for a PvE buff. Why not allow Thorn to over-penetrate Solar, Arc and Void shield of enemies? Maybe even allow it to pierce Kabal shields and Hydra shields? Just an idea that kinda fits with the gun and it's Exotic rarity. Maybe you could choose between the damage over time aspect and shield penetration. Bad JuJu on the other hand is just kinda all around bad. Maybe have a debuff placed on shot enemies that increase the damage done, or if all shots of a burst connect a 4th shot is fired from reserve ammo? Any way just an idea, but It would be nice to actually use Bad JuJu, it's a pretty badass looking gun.
