They [Jagex] need to make a mix of OSRS gold Smithing and Mining Guild. You would need lvl 60 to be able to join however, it is important that players who are simply excellent miners/smithers to have doors to separate them. Mining Guild Re-Vampedc’mon seriously, around 5 mithril rocks and 30 coals. 15-20 mithril is the best and includes 10-12 adamant, 5-10, and 3-5. There are also some 8-12 gold. This would make the guild very popular and overpopulated so maybe not the runite part.
Smithing Guild. What are the two most important parts of Smithing? That's right, anvils and furnaces. There's nothing else to add about this aspect of the guild. I would also recommend a shop that allows customers to buy or sell ores/bars that the mine/smith is able to produce, however since it's an NPC shop, the amount you receive from selling them would be lower, and the purchase price will be slightly higher than G.E. (this is to discourage people from staying there sooo long while earning so lots of money, and encouraging them to leave and bank) You are welcome to comment on any flaws.
It was an idea I tried to share on the official rs forums. Since nobody responded I decided to try posting the idea on sals. For buy RuneScape gold a start my concept, I'm thinking of zombie wars.
