Considering Blizzard intend to remove Layering from WoW Classic during Phase 2 of their content roadmap, allowing people to move freely was inevitable. Fortunately, they're bringing it around sooner rather than later. On my server, where my friends and guild are, there's prime-time queues of over 10,000 players. If you don't login by 2:30pm, there's no chance of playing that evening. Just to stand any chance of playing, I've had to resort to using Remote Desktop login, if I don't happen to be at my desk at that very moment. Full details below. 

We are working to open our Free Character Move service for select WoW Classic realms in the coming days.

When free character moves become available from one of the most highly-populated realms, players will see the option to initialize a free character move on either the character select screen or the queue screen of the realm.

To best prepare, please note that a character cannot move if the character:

• is a guild leader.
• has active auction listings or bids.
• has mail.

We will post full details about the realms available and character restrictions when we open the service.

Thank you!
