Hmm, copper and tin much frequent than iron (about 3 times) and used much less than iron, so it is easier to get. On other hands - it needs machines and energy, but cost for full set is not bigger than stack of charcoal in generator which is again pretty easy to get. Besides people usually build a solar arrays pretty quick, so energy is actually not a trouble. And than usually comes nano suit. I might be wrong, but it seems that bronze armor lasts much longer than nano suit.
And GregTech has a mortars which are completely cheaper than machines.
I think solution may be to nerf bronze armor and add full set of composite armor. It also will answer to question - why the bronze wrench is wearing out in compare to electric wrench which is made from iron.
Just my vision.
P.S. As we talking about bronze, I have a question - why electric tools have a (probably) bronze hulls, but we did not use bronze in recipes?
I was popping in to Support to see if a new beta came out, but I found this thread instead. Here's some fun facts I've learned about Alblakas' armor balancing choices since IC1 and beyond:
-IC2 bronze is stronger than bronze-age bronze, due to an effective alloy blend. Modern day bronze is FAR stronger than bronze-age bronze, because we have tools that allow us to find the best molecular blend of metals to make the strongest alloy.
-Metal armor IS stronger than nano armor now, but that is because electric armor is rechargeable. You have to put in some real work to get a new set of metal armor.
-If we go into the fictional debate between fictional bronze and fictional iron, then I would like to argue that Alblaka's fictional refined iron has a higher carbon content than fictional MC iron, which is why the electric wrench does not break down like crappy fictional MC iron tools. Not only that, but it was made with a better fictional manufacturing process.
What I'm trying to get at is Alblaka made a mod that lets us feel high tech - nowhere in there does it say he has to be realistic, especially when it comes to balancing it so people can enjoy playing together in multiplayer.
