Im a bit confused here. This thread was posted a month ago stated that 2 guilds will be raid testing. So if its out in the open then why does the guild need to state what has already been stated?
Those tweets do not show that they were testers, just that they completed it in 15 minutes. That looks downright awful to people out of the loop and makes the new endgame PvE (something a lot of people originally slated this game for not having) look easy and worthless.
