Yeah, Bungie is full of it. I've done it three times a week every week since this raid has come out and still no Eyes of tomorrow, even after the patch where they said its pretty much guaranteed for anyone who has been playing it since launch and it doesn't matter if it is a subpar weapon, I've been trying to unlock this title and bungie's shitty RNG is the only thing keeping me from it. If the vex mythoclast is locked behind this kind of bullshit RNG I might even just stop playing this game entirely.
