I knew about the class kills Grimoire being bugged and made a reddit post a while back, however it's hard to get evidence for it. It's the middle node of Crucible kills with all 3 classes, all dont grant the 5 pts so that's technically 15 pts that have always been missing from everyone's scores. And like I said, hard to get evidence because you must take a picture of your score and the node right before it levels (so they have to be within the same screenshot, not sure if possible) then you have to screenshot again in the same way right after. That said, I'm glad you know about it, and I now have a place to post my findings.
