I did some searching for this question and I haven't seen anyone else complaining about the problem. I run a celestial healer with consume soul, renew, and guardians light 4 my main rotation. Consume salt spam and renew to charge purple healing ray with the intention to proc using guardians light. In recent raids, after the upgrading putple, I notice guardians light does not receive the cooldown reset when the purple healing ray Procs. renew does, and I think consume soul does but not the heel I really want to reset. Has anyone else noticed this?
Only group + priority heals proc PHR. Admonish is the group heal and Renew is the priority heal. Guardian light doesn't proc PHR.
