Don’t mind me - just dropping this here as a reference in a bug report.
Following several complaints on Xu-Fu’s of problems with the Pandaren Fire Spirit battle, I decided to take a look.
This is NOT the known “pass”/“stun” bug, though it could be somehow related.
As Avaren said there “the battle is skipping 2 rounds and reducing the PFS cooldown on Conflagrate, but not for Anubisath Idol’s Deflection. My battle just went round 7 (Conflag | Deflection), proceeded as normal, but then skipped round 10 and 11 (Immolate ticks only), and at round 12, PFS cast Conflag (4 round CD), but Deflection (3 round CD) wasn’t usable.”
I posted a response at https://wow-petguide.com/Comment/101236
Here’s another view of the relevant rounds:
Nothing we can do until Blizzard fixes it.
P.S. Remte just told me that the original battle had PFS actually scripted to pass there, so it may be just a result of the pass/stun bug,
