Yeah honestly it has way too much utility. To keep it's damage above RDM but below BLM i would make minor adjustments to the utility still.

Make the shield spread CD 2 minutes even if it breaks. Remove the heal from Star Prism or make it a barrier. Make the raid buff position based so people have to stand in the circle to get the damage buff, this would still make it strong but clearly SMN and RDM utility would be way higher.
I would for sure want PCT to be at least the second highest damage but there's no way something with this much utility must surpass BLM, it's already been gimped enough with it's rework.
