Leveling Jewelcrafting is fucking expensive

Enchanting is great if you want to make money from disenchanting. Making money from enchanting things is not quite as good, in my opinion, but it's a useful skill to have to enchant your own gear.

Mining makes KILLER money at higher levels, BTW. A single stack of adamantite ore sells for 30g on my server. On top of that, you get motes and such as well, which often sell for ~2-3g a piece.
