Is every world of warcraft disk bound to the account?

[Atanalcar]

It's not the discs that are bound to the account ... it's the cd key that comes with the disks. You will be able to install the program, but you will not be able to login at the same time that he does. You would need to purchase the game again and create your own account if you want to be able to play at the same time that he does.
