U must not have much stuff then...cause i use the hell out of em

If you don't upgrade weapons often then you'll end up with a surplus. It also depends on what materials your weapons/armor require. On my warlock I never seemed to be able to collect enough helium filaments as all my armor and most of my weapons took helium. I spent a lot of time on the moon.

I agree
