I know im not the only one who noticed how drop rate for Banshee mods (which are most useful) is very low.
It takes a while to farm 2-3k of gunsmith materials and from that you will get maybe 3-4 mods IF you are lucky, and chances are 50-50 they will be trash / something that you'll never use.
I was not so much of luck after I spend over 15k gunsmith materials so far just to fill less than half of collection. And yes, I still dont have mods I need the most.
Seeing as how I have 10k plus materials is rather buff how much I can give to him. Takes 200 to get a engram and you can only give 25 at a time. I want to give 200 at a time to speed it up if I ever needed. That’s why I chose my 5k crucible and 3k vanguard tokens to trade in for mods instead.
