It's a no-no, you think you'll play your character for WOW Classic TBC Gold a while in Classic but you'll never particularly if you've already cleared Naxxramas. You can always start over with a different character , if you'd prefer to remain playing Vanilla. It's much more fun and rewarding.

Players who want to play max but don't have the funds to get there yet. They can either use changes to tbc or staying in the traditional. They can join new guilds, and begin to raid nax entirely starting from scratch, with a brand new raid. They'll need to pay for a service to copy them to join with tbc. Since the original community of WoW has been dissolved this service must be free.

The servers that are currently in use will change to TBC servers. You can open new Vanilla versions of these servers. You can choose between activating your character on the TBC server or the Vanilla version. You will need to pay to activate the same character on both.

Edit Note: This article came from Blizz. On the day of patching, you'll be able to access the Battle.net desktop and select the game you wish to play: WoW Classic or Burning Crusade Classic. Both game types will display your characters that are currently playing under the old realm name/s. When you have chosen a game, select the character you want to play and confirm. There is an alternative paid service to gain access to the cloned character of buy WOW TBC Gold each game type if you decide to play as your character on both. All you need to do is sign in your account as usual and play.
