Every old hand at World of Warcraft would tell you that professions are a really beneficial part of the game. They act as your bread and butter--do all the dailies you want, but if you really want to pull in the gold nothing works better than having a maxed out profession. Like in Burning Crusade, Wrath of the Lich King and Vanilla before it, Cataclysm professions are more or less the same. I prepared this guide in the hopes that it will give you a few pointers.
In Cataclysm, professions are separated into two different kinds: primary and secondary.
There are 10 primary professions:
...And 4 secondary professions:
All secondary professions can be acquired, where as only two of all the primary professions can be learned. Primary professions are your moneymakers, while secondary professions are more of the practical variety. All of them are valuable assets, however.
Primary Cataclysm professions can be categorized into two types: gathering and crafting. The gathering professions consist of skinning, herbalism, archaeology and mining. A couple different crafting professions are blacksmithing and engineering. Speaking from experience, it is wise to have one crafting profession and a gathering one. Items you can find with the gathering professions find their uses amongst the different crafting ones. Although the thought of being able to both make your own armor and socket them with your own self-made gems is alluring, without a gathering profession you would have to buy all the necessary supplies from other people or the auction house, and most likely at extremely high prices as well. Not to mention, as a gatherer you can put your own materials on the auction house and make a profit off those too lazy to gather the supplies themselves.
The following are a few of the most useful cataclysm profession combinations (crafting/gathering):
A 525 skill level is the maximum all cataclysm professions can be leveled up to. For best results in your crafting professions, try and prioritize the crafting of items in this order: orange, yellow, green. Orange items take both more and rarer materials to craft, but always award you a skill point. Yellow recipes do come with the possible risk of no point coming out of it, but the odds aren't so bad. Green is more or less around 40/60. As expensive as they may be, you ought to make orange items whenever possible.
Above all else, building your professions takes a lot of effort and diligence. But as the old saying goes: 'you reap what you sow'; and a max profession is one of the most beneficial things you can have in World of Warcraft.
