I've been at it for about 7 days, still on 2/12. Granted I'm not just grinding it for 12 hours straight, but I'm probably up at around 60-70 completed FATEs. Would be nice if they kept the grind but removed the need to sacrifice something to RNGesus to be able to get them. Books sound fine.

I'm looking forward to seeing whether any of them are able to get all their atmas
