I am starting this thread to help someone on Twitter (Benni) more thoroughly. His BiB result is showing 2 of the same essence on his Holy spec (Mythic+). I cannot reproduce it and I have had him refresh the page as well as switching to every spec in game and then generating a new string.
He also reported that we are recommended in a ret ‘talent’ in his holy spec, and I suspect that is referring to an AZ trait with holy not as the top priority. Following up on that.

Let me know if I left anything out Benni.
