K so yoshi is putting it like this,
Atma is for weeding out the lazy and ppl without time to spare.
Animus is for weeding out the people who are burning themselves out on bray hm and ppl without more time to spare on the 3 fates.
Novus is for weeding out the poor, the bards , and the ppl who don't have access to ppl that can help them.
After all that we are left with ppl that have a lot of time to spare, have a lot of gil and the will to grind more fates for extra alexandrite.
