Hey there! My team of 3 did all of the nightfalls this season. We used destiny.report to judge our times. We expected only this seasons times to count, but found that previous seasons did as well as 2 members got the emblem before we had done all the strikes. I’m sure you are aware but there are some instances where you can just be that little bit faster, or get that little bit luckier, to get what we called a “gold star” time. For our last fireteam member, who got it this week, we were pulling our hair out trying to improve our hallowed lair time as that was the one we hadn’t gotten at least an “outline” time, but went and improved our insight terminus time by ~30 seconds, and they got the emblem immediately. My best guess by looking at all of our times, that 30 second improvement pushed them under 120 minutes collectively, which could possibly be another requirement. They, (and I actually) don’t have an “outline” time on HL, but both have the emblem. I hope this helps!! Best of luck!
