As long as it's an already used currency... Because ,dear God , more types of currency is the last thing this game needs.... It shouldn't even use notes of light... Should use ascendant materials or just weapon parts but the trick is that to put the perk you want on the gun you have to find a gun with said perk on it already... I want shot package on my legendary shotgun... I just have to go find any shotgun that has shot package... Take it to the gun Smith... Have him "salvage" the gun perks... Now it. Can be placed into the slot it would normally go into for a fee of some weapon parts but also you have to complete some mission that he assigns or something.... Idk make it fun Also you can't break an already broken PvP lol... There are obvious better perks in this game... And if you made a system where people had more customizable gear they wouldn't feel like they are getting butt fukked because they weren't blessed by rngesus... Adding easier customizability would help alieviate issues rather than create them.
