While I agree with just about everything you said here one thing I will note is that the gear isn’t really a problem swapping jobs because the cryptic way they list occult effects obfuscates the fact that the occult effect is really weak

If you have the best occult gear possible (a full set of +2) the 600 main stat and the 15 special attribute contribute overall 13.5% damage and 15% phantom action damage. So the punishment for swapping off occult gear to a different job unless you are going from +2 to nothing at all amounts to basically losing like 5% damage

Other than that I agree with just about everything. OC is too fast, a lack of forked normal breaks its gameplay loop and you can really only play around with phantom jobs (which are boring anyway) when you have all 12 mastery stacks
