You're missing the point. Nothing in this game should cost only 10k to create. There should not be 50 raw gems for every player on your server.
Please supply your reasoning on why this game should be as you describe.

If your thread isn't about improving the game's economy then don't title the thread as such.
Improving the game economically. <- thats the title; or in other words, Improving the game by adjusting economically related aspects of said game.

Anyways, I would invite others to join in on the original suggestions and original discussion as per the title.
