Different Armor haveing unique uses

I feel like the current armor system is too linear, and some armor types like chainmail, gold, and leather don't have a big enough use to have a full set of them. Gold already has the unique aspect of enchanting easier, so what if gold armor and tools could go over the enchanting limit? This would add a reason to use them despite their low durability. Chainmail is very rare, not being craftable, so I feel like it should be accurate to real life and reduce damage from physical attacks. Leather armor is more cosmetic, but it would be cool if it had a slightly faster movement buff since it is lightweight. These changes would allow players to chose how they fight in PvP or PvE with their armor choice.
