Some cool ideas, honestly though with the strongest ones you have here, going from some of the vid docs a year before launch, that was exactly the system, no materials needed to upgrade weapon perks but weapons had level and they could be upgraded and carried with you through your entire character experience while still being effective, kinda sucks the system now is..."here's a really cool weapon, you'll get used to it and love it but will become irrelevant once you level alittle" :(
