Correct. We’re able to turn on content such as Dire Maul or World Bosses without having to change the game client and require downtime the way a patch does.
Sorry for the confusion.
Yes – the Keyring will come to WoW Classic with our first patch to the game client later this year.
We don’t yet have a certain date for the patch, but we’ll let you know as soon as we do.
