Crafting in Wow is much easier. The crafting system is setup completely different. You "train" or learn a tradeskill by spending skillpoints. Skillpoints are attained by killing mobs. You make money crafting immediately. At early levels the "gathering" tradeskills are the easiest way to do this. You can learn mining, herbalism, and skinning. The materials gathered by these tradeskills are used in other tradeskills.
Mining is good for Blacksmithing and Engineering.
Herbalism is good for Alchemy and Enchanting
Skinning is good for tailering and Leather Craft.
In the early levels you can sell the materials you cant use for profit.
Mining, herbalism, and skinning can be failed. However, if you fail, you can just redo the action and it will be successful the next attempt or two.
The "production" tradeskills (Blacksmithing, Engineering, Alchemy, Enchanting, Tailering, and Leather Craft) can not be failed. You learn new recipes for these by purchasing them or getting them as drops from mobs. The recipes are color coded according to your level in that craft. This may not be exact, but this is what I have found when crafting:
Red = always gain a skill point
Yellow = gain a skill point most of the time
Green = seldom gain a skill point
Back = almost never gain a skill point
I have left out some tradeskills like fishing, first aid, and cooking because I have little experience with them. Hope this was helpfull.
