If you want to level your chars using this method, you need atleast 10 000 gold to invest at start, more gold you have faster you can do it.
In order to level with this method, you will simply have to go to AH, check prices of vegetables/meat (ingredients used for feasts etc.) and buy them if the price is low enough to make profit.
Blizzard Entertainment has announced the opening of beta registrations for “World of Warcraft: The War Within,” inviting players to explore new subterranean worlds beneath Azeroth.
Danish from eXputer: "Despite Blizzard's attempt to give a fresh new spin to World of Warcraft, some fans still seem to be stuck in the past."
