I just reached level 200 in Blacksmithing. I'm also a Miner. Don't go into Blacksmithing as a way to make a lot of money. The metals involved in the craft are the least of your worries. The rare stuff like gems, rare earths, leather and even things like flux often have to be purchased in order to level up significantly. I have found that for most Blacksmith crafted items at or below my level, it's much cheaper to purchase at the Auction House (even at buyout prices) than to make it yourself. Maybe this changes with Artesian crafted items... I'll see. Last night I made six "Green Iron Helms" to get to level 200 and had to sell them at or below vendor buy prices in the Auction House. I wanted to get stuff with "Made By: Me" on character's heads.
Don't ignore cooking. It seems like a lot of folks do. Higher level dishes grant a 15 minute buff of 10-12 on both stamina and spirit. Kind of nice when youre grinding.
