I think most people are complaining over the RNG factor than the grinding part. You don't see too many people complaining about the 13.5k mytho for the books nor the stuff you need to do per book for that tiny stats boost, do you? I do like the ideal of getting Atmas from FATEs since it make the open world more lively and potentially help out the new players to gain some levels, and we do get FC seals from it as well. I think all we need is a little boost on the drop rate (either flat increase or linear increase over time as you stay active in the zone) and everything will be good to go.
