The flow is really awkward now, before at least using the naive rotation it looped pretty cleanly (I never messed with -18 FoF or whatever and still did fine in extremes and such, although I did play around with the 2.5 GCD rotation for a bit before 6.3). I was assuming you'd have to drop atonements somewhere to keep it lined up but I'm seeing people suggest hardcasting Holy Spirits, both of which I'm not a fan of.
Edit: On the upside, there would be some flexibility in choosing when to use your Holy Spirit so you can time it with disengaging from the boss if needed
