I know they stated to the contrary.

But I don't think it should be the case.

Why? One set of Atma was enough... a second set for a current subclass is enough... a third set & subsequent sets for every next Job release, too much.

If it weren't so insanely RNG-based, sure.

But a person can easily spend 40+ hours collecting 12 Atma's. And the process is quite dull.

Having to Animus/Novus+ the Ninja is good enough IMHO.

Additionally, I think Atma should've applied to subclasses to begin with if that matters.

You still need insane amounts of myth, you still need to unlock the Relic Zenith, you still need Novus requirements, etc.
