According to a post on Blizzard's forums, five new realms are going to be added to World of Warcraft: Classic soon. Among them, Nethergarde Keep will be a "normal" realm while the rest, Flamelash, Gandling, Mograine and Razorgoreare, will all be PvP realms.
Not only that, but Blizzard also announced that the limitation of only being able to create a total of three WoW Classic characters per WoW account has been removed, which means that players can now create up to 10 characters per Classic realm, for a total of 50 characters across all Classic realms per WoW account.
The update will go live later today, as of writing. For more details you can check the official statement here.
Are you happy with the addition of more character slots?
