Ok yes... I know its another profession leveling guide... However, I believe that this is the BEST guide out of all the other profession leveling guides out there! It is a smart guide that enables you to really lower your net cost through the use of DE and reselling! This site not only gives you a guide to powerleveling your professions, but also provides gold guides through the use of the professions. They also provide Excel files!

Rules to leveling professions:
"General rules when leveling crafting professions
1. Spending more mats on something that is more desirable or gives a higher DE value will give you a smaller net loss.
2. If you have to sell items, don’t list them all on the same day. List 1-2 items at a time
3. Have an enchanter handy. Either one of your other characters (strongly recommended even if it’s an alt you rarely use) or a friend that you can trust, and just give a tip to DE the items.
4. Look for the smallest net lost, not the cheapest to make. Sometimes it’s the same item, sometimes it’s not.
5. Profits will vary by server. If you have a lot of people DE’ing for profit you won’t make as much back. If you don’t you will make quite a bit of gold.
6. You may be making things that don’t get you a skill point every level however, you are not “losing” gold if you evaluate the cost, AH value and DE value properly."
Example of the professions guides:
Jewelcrafting - "Jewelcrafting is one the least expensive professions to level when you consider the net cost to level. Since you can make gold off selling most gems in the last levels for more than it costs to cut, it’s a profession that actually reduces in “net cost” per level as you get higher."
Example of Gold Making Guides:
Each profession section contains a Crafting for DE. Here is an example.
Sorry for the wall of text? Just wanted to let people know of this site! It's helped me gain tons of gold through the uses of these professions + playing the AH. I do not claim to own any of the site's content. All credits go to the creator of http://www.wowconomics.com
