As I was doing Vault of The Wardens, our healer disconnected so me and the rest of my group decided to start jumping in the pit right before the last boss but suddenly as we were jumping in, this message popped :
"Is this what you usually spend your free time on? Seems like a poor use of your time. Never fear, I will have more directions for you later."
I quickly asked whether anyone else from the group saw that message and they all said no. I've seen some posts saying that a GM said that the hidden appearance is connected to Vault of The Wardens. The only doubt I have is that this message might be from an addon, but it seems too vague and useless to be from an addon. Since I just created this account only to post this, I still can not post pictures
. Will upload as soon as I can.
