Bungie, Banshee-44 cost wayyyy too much gunsmith materials to rank up for a weapon. 100 is quite a bit. We need to dismantle 34 different legendaries items for us to rank it up. I understand why you did it, but most of the stockpiles of Gunsmith Materials are gone now, and it's a struggle to find Gunsmith specific weapons, or try to find weapons we like with good rolls. Regarding Masterworks and Enhancement Cores: Can we please have a way to reroll Masterworks? Make it cost like 10-20 cores, and reset the Masterwork to level 1 if you have to. I have so many decently rolled weapons that are just lacking that MW to make them good. Especially with bows. I recently got an Archer's Tempo/Rampage Subtle Calamity I've always wanted. My first one. However, it has a Stability Masterwork. I reallllyyy want Draw Time... however I will still use it here and there because it's fun. What isn't fun is trying to farm for another world item that doesn't drop much... only to get another bad roll. So please, allow us to reroll Masterworks. Thank you! Of course, all of this are my thoughts and opinions. tl;dr: Gunsmith costs too many gunsmith mats. Please allow us to reroll the Masterworks on gear(at least weapons).
It should cost 50 at most because he offers nothing but junk, just like the vendors on the planets who require around 50 or 60 resources to rank up.
