You are most likely here because you enjoy crafting. I have been reading up on some of the WoW issues regarding gold making, which make me realize that WoW is not the game for me.
If you want to play a game where gathering and crafting is the cornerstone of the economy, and are not faint of heart, I recommend EVE Online. EVE even has releases purely to support industry. You can play for free if you are good enough manufacturer or trader.
