I've done vog since it's release. I just got PF last night. The stats are insane. I've gotten 10 Vex, 2 timepieces, 1 fatebringer, and 4 VoC. Those seem to be the most sought after, and rarest of all vog raid weapons. I've only seen 1 other person get PF when doing the raid. I shall level this new toy up, and use it for Oracles for now on.
