So, since the servers are up, a couple of things,

Requiescat is to buff the Confiteor combo.
If you were to do the full 3 Atonements and Holy Spirit off of Royal Authority, the filler combos will drift from where you started by 2 GCDs, which does matter since you will be using Holy Spirit/Atonement/Royal Authority in the buff phase. How this will affect things I do not know yet, but it is worth mentioning.
