I think the armor and weapons (the tradeable ones) should cost more emeralds because of scraping items. When you buy, then sell the items to the blacksmith you earn no profit. But if you buy, then scrap the items to the blacksmith you can sell the scrap on the market for around 10-12 emeralds thus turning a "free profit." My suggestion is to make the tradeable armors and weapons above, at least, 14 emeralds. 14 emeralds should be low enough so low-level players can easily buy and marketers can't abuse. UPDATE (7/9/2020)- This is an update on this idea which changes the argument of this article. Read this before you yell in my face. Second idea: Instead of jacking the prices tenfold from what they are, increase the prices of all tradeable armors by +2 emeralds, +1 emeralds for the tradeable weapons. By doing this we can keep the items purchasable, incentivize grinding for emeralds by a bit to grab more emeralds, close the gap of scraping then reselling the items quicker, and to make the buying range not look awkward.
