To craft low tier armors the recipes require too much materials. Leather Jacket and Helmet have decent requirements but the fun starts when you want something higher. Let's see the prime culprits:
Combat Leather Jacket
5x Gecko Pelt
2x Golden Gecko Pelt
1x Fibers
1x Leather Jacket
Combat Leather Helmet
1x Gecko Pelt
1x Golden Gecko Pelt
1x Fibers
1x Leather Jacket
From these I would propose removing the Gecko Pelt requirement altogether. You already used the Gecko Pelts to make the Leather Jackets. Next in order is the Leather Armor and Helmet MK2s:
Leather Armor Mark II
1x Leather Armor
2x Golden Gecko Pelt
1x Brahmin Hide
Leather Armor Helmet Mark II
1x Junk
1x Golden Gecko Pelt
1x Leather Helmet
Golden Gecko Pelts should be removed altogether from these recipes since you use them to craft the regular Leather Armors.
I would lower these requirements even more, but lets see first what the community says (just see how simple the Combat Armor and Helmet recipes are, it's pointless to craft anything else).
