I dont know, Id take a quest for each atma to kill 100 fates in each area of the overworld over the way it is now. It would take some doing to complete 100 fates for each and every atma but at least I can see a quantifiable end to it. How it is now, its merely a slot machine pull. Some people are super lucky and some people are super not. There are people who completed the whole thing in about an hour or two, others spent that same hour or two and didnt get squat. Myself... I sat in an area for over 4 hours before one actually dropped for me. I havent bothered to go any further in the chain. The books themselves should have been the grind, since they really are.You work for the points to spend to buy them then have to do a series of things to finish it. The whole atma part could have been made easier because honestly you are putting forth all that effort for really zero reward. You dont even make the weapon better, it just gets a different little glowy effect. Really? Oh and the privilege to grind out books.
Of course people will defend it by saying it was meant to make you smash your monitor in frustration after the thousandth fate with no atma. No effort, no reward. Right? Bollocks!
