I've started leveling Jewelcrafting recently, and Im still only in the 100s (At 140 I think) and it seems like a fair expensive profession to level since a lot of what you need to make in order to gain a skill level requires a lot of materials.
I'm wondering if it will truly be worth all the trouble by the time I get it to 450. I have been thinking about picking up Inscription instead since Glyphs seem to sell for quite a bit on my realm.
