PCT is insanely strong solely on Ultimates, because the job heavly benefits from downtimes and FRU has... a lot of downtimes. If you take a look at every other content in this game, you'll notice PCT is not always top1, the ranking board is not full of PCT or the disparity between a PCT and another DPS job is not as glaring as it is in FRU (especially in COD).
The real issue is the job having a DPS comparable to a BLM while having SMN party utility, they should just make a choice instead of having both of these in a single job
