I quite like how it works. FATEs are highly accesible content, making it very easy for someone like me who is trying to squeeze atma farming time in between everything else and work... sure, I spent a long time in Western La Noscea, and I currently only have 5 atmas... but I'm chipping away as and when I can. Also, it's not like you don't get anything from FATE spamming... FC points, GC seals (which I'm burning through pretty fast on ventures) and a little bit of gil to boot.
That's my thoughts anyway!
