I think it sits somewhere in the middle
Saying the second least mobile class is basically a physical ranged is stupid (though that wasn’t the original point, they simply said it could be designed as a physical ranged implying more along the lines of the fact that the jobs freeform nature doesn’t necessarily have to work with casts. PCT with zero cast times and nothing else changed would still be a playable class) but PCT’s Freeform nature also allows it more movement ability than a generic “oh it spends 50% of 120 seconds casting so it’s super immobile”
PCT really only has a few hard rules
1) you must enter starry muse with a comet, wings/fangs and a hammer stored
2) you must use your off minute hammer as well as the other 3 creature muses + mog/madeen outside of starry muse
3) you must not overcap paint gauge
Beyond that you can do literally whatever you want with PCT’s rotation
So it ends up way more mobile than BLM despite casting about 85% as much simply because you have a lot of options for movement at any one time
