Bug description: It is low priority, but there should be a way to award this achievement for the players that had all the criteria after the fix, either retroactively after a restart or through finishing one more quest/class hall mission/etc., you can see in the proof that there are a lot more players that completed the necessary quest (and I assume that most finished their class hall campaign and broken shore if they did this many keystones, anyway this was done mostly on mains).
Proof: Light's heart

Confirm !
