I know the feeling. Spent 9 hours total myself farming fates(yes with my zenith equipped!) before i just had to stop. Was especially disheartening when I was around the 6 hour mark an FC mate logged in, asked how to start the atma quest, i directed em to it, he goes to start farming as well and in the 2nd fate he gets his drop. Also as you said, I would much rather spend this time on actual hard or new content. But just spamming fates which i have already done for the umpteenth time for stuff is just not fun and engaging. It is a boring time sink. One I am thinking I am just going to skip. Maybe if i could do these fates as a lower level class and actually make the time worthwhile I could then definitely see doing it.
