I just got an "Aspect of Glass" ship, an Atheon's Epilogue, and FINALLY got a Vex Mythoclast from VoG (Hard, of course, because of the Mythoclast).I just wanted to let players know a tip (that a few people already know). You have a WAY bigger chance of getting a Mythoclast if you beat Atheon Hard FLAWLESS. This means no wipes. If you want to, you can go to orbit and back to the raid with your team to reset your deaths. I hope this helps.
