only way...buy the game
There is no one person who made World of Warcraft. The team at Blizzard created the World of Warcraft.

There is no legal way to get "free" authentication keys for World of Warcraft. You must purchase the discs or use the blizzard store to purchase one.
You don't have to have a special account, but you have to of made a regular World of Warcraft account and have the Burning Crusade with an unused authentication key.

When you buy World of Warcraft, there will be an activation key. You have to register for a battle.net account, and use that key to link your new game to your account. You have only 1 Battle.net account, but you can have any number of Blizzard games listed under it.
You will still have to pay the 15$/mo. -- If you do not want to pay a store for the installation media, you can download the installer form the World of Warcraft site.
