Hey guys, an idea JUST popped into my head right after I was reading some other suggestion threads, and I don't think that anyone else has asked about this. So, my idea was that certain ores, hides, fabrics, etc wouldn't just be used for light/medium/heavy armor. For example, an ore that is very light and flexible (maybe aluminum?) could be used as a medium armor, instead of a heavy armor like most metals. Another example would be leather from an animal with a very thick hide. The hide could be used for heavy armor, due to its hardness and weight.
