What is troubling is those who are looking to complete max, but don't need to do it due to changes to the tbc system or stay the old school and find new guilds and start playing nax raids from scratch by creating completely new raids. They will need to purchase a service that will duplicate them in order to start tbc. Because the original wow community is no longer in existence, the cloning service should be completely free.
All servers currently running will be TBC servers. New Vanilla versions of these servers will be made available. You can choose to activating the character either the Vanilla or TBC version. It is necessary to pay if you wish to activate the same character on both.
