a little late I think I have actually deleted the screenshots I took when my guild did it. I do recall at the time checking the 8m and 16m thread my guild came in world 4th and server first for prophecy of the five. Think we did it on 12-12-12.
Yeah, I do know that the guilds on our server that have it are -
Tatooine Royal Navy 12/12/12 8:09pm PST
The Silver Order 12/16/12 10:17pm PST
Hatred 12/18/12 Unknown time
Like you and I both said, a lot of people deleted their SS' of this by now lol or just didn't bother taking an ss
