Ugh...
"What's the quickest way to....."
"What's the best money...."
"What can I make the most, quickest..."
These questions are... well, they get old after awhile. Remember, this isn't your Single Player RPG. This is an MMORPG. If everyone tried to do "The Biggest Money Maker" then it would quickly dry up, and everyone would be complaining about everything -else- that's hard to get.
What you need to remember in an MMORPG like this, is that we need a diversity of skills. If, say, Enchanting was the No.#1 thing to make money, and if Everybody and their neighbor did Enchanting, then it'd be harder to skill up Enchanting, and there'd be far far too much competition. Well, the Green Item Sellers would be in pure heaven though... lol.
But then, other professions like Mining, Skinning, Etc would suddenly increase in profit becuase not very many are doing it, etc. When choosing a profession, sometimes its best to consider what your character is, and what your goals are. At the end of each Craft, the meat (IMHO) of each craft, are those BoP items you can make. Are you choosing a craft that has BoP items your character will benefit from? I made a Warrior on Dethecus and I chose Enchanting and Tailoring. Now, I know I'm missing out on BoP stuff that Blacksmithing could make for me, but I went into it with the Mindset that I could give myself Free Enchants, to further bolster my equipment. I chose Tailoring, because, if I chose Enchanting, and Smithing, I'd either have to rely on a Guildie to get me my ore, or pay gross prices on the AH. Now, maybe once I get Tailoring to 300, trick myself out in 18 slotters, and such then I might consider dropping Tailoring and picking up Smithing if I have need of it later, who knows. Maybe by then I can easily buy my ingots needed to make my stuff.
