It did not happen in Wrath. You couldn’t even vote kick from the start (though some people got the ability later on), so you couldn’t hold a group hostage. And if you did get kicked you still got the 15 minute dungeon cooldown! There’s literally zero point to try and hold a group hostage. You can’t requeue.
By the way…
Keep thinking I don’t know how the system worked. I remembered a damn blue post from 14 years earlier.
