I'm not that worried about PCT damage for savage, it's just BLM (and really the casters in general) that need to be buffed.

I am worried about PCT in ultimates. The job already completely nukes trash pulls in dungeons with the way you get muses back, but that doesn't matter because that's just dungeons. However being able to cast muses during downtime in ultimates has the potential to create a huge balance problem, you can already see this in the limited data we have on legacy ultimate clears.

It's possible to design around this (have the downtime prevent any casting, use cutscenes/down for the count, have long uptime phases) but I don't like how the job gets so much stronger with downtime relative to all the other jobs.
