We have plan to include the Dungeon guides as free update, I don’t think any holidays exist in Vanilla, will include WorldMapTracking as free update, other things like pet & mount might be a small free update as well as there isn’t a lot of them around.
That’s awesome to hear it’s at least possible. I know it will take time as initial focus will be getting the existing content finished and pushed out while still supporting retail. As stated holidays were confirmed in the Reddit AMA but regardless I’m happy to have your guides to emulate Vanilla years ago.
