I love the Atma book grind, except waiting fir Fates to spawn
The Atma book grind is almost a perfect design of a grind. You keep busy with a variety of activities while seeing a steady non-random progress.
The only thing that breaks this otherwise enjoyable grind is when you have to wait for a specific Fate to spawn. Here action stops and you may be forced to pretty much just stand around watching the screen for hours.
If they had changed the Fate part to do 10 Fates in a specific area instead of do this one specific Fate it would have been perfect.
