Downed it at 8:22am GMT, no deaths, just a DF oneshot with me and 2 other guildies - was queued for about 35 minutes before, that being the first pop. Done it three times now, one shotting it each time, as our FC members keep unlocking it. (To have a 8/8 premade for the obviously harder EX mode soon). The fight is not hard at all even completely blind. Like, not even Titan HM levels of hard.
