@Hydra, you do realize that bronze armor gives the same amount of protection as with diamond armor (except for the enchantablity and durability) right?, and you are starving of copper mainly because of TE world gen that's used in FTB, change back to IC2 copper and you'll see the difference.
Regarding the protection: sure, but you only need very few pieces of bronze to create armor. Unlike the forestry machines (some of which require like 24 ingots for a single machine, and then there's the ones that also need copper). The point is that GregTech needlessly nerfs a recipe that is hardly used in the mod it's an addon to anyway. I think GregTech would not get all the 'hate' if he would stop messing about with pointless changes like these and just focus on adding new nice stuff instead.
