So the main platform outside of the Caverns of Time for the anniversary event is where a lot off questgivers are like the guy who gives a daily trivia quest. To reproduce this:
- Stand by the trivia guy
- Queue for Headless Horseman daily
- Do the event and then leave instance
- Maybe 1 time in 20 you appear below the stage
For small races like Vulpera you can actually get out of the gap there next to the stairs. But even Dark Iron Dwarves are too big so you have to hearth. It’s kinda of annoying.
It doesn’t seem like the game is built for that platform being there.
