To craft some small energy cells you need:
-6x Electronic Parts
-4x Minerals
-4x Ore
Isn't that a bit much on the electronic parts? You only get 5 from one gathering session and the places where you can get them a few, remote and unguarded.
This is entry level ammunition for energy weapon users, it shouldn't be much harder to craft then 10mm JHP, .44 JHP or 12 ga. shells... and you can easily craft 500+ of these other ammo types from the ore/minerals gathered in one go (in a safe location).
I'd love to make some SEC from 3x Electronic Parts, but I could live with 5x or the option to craft 50 pieces from half the resources (3x EP + 1x Alloys).
