It took me about a week and a half of grinding, at two hours a day, to get all my Atma. Am I glad the grind is finally over? Heck yeah. Do I think the grind is just fine? Heck no. It needs to change. There were times I got so frustrated with the grind that, in order to keep from breaking my keyboard, I had to quit playing FFXIV and go off and do something else. I'm personally hoping that when 2.28 goes live, they at the VERY least, lower the Myth costs on the books and/or increase the drop rate on the Atma. Just making the books cost 1000 Myth rather than 1500 would make that part much faster, without needing to 'nerf' the actual challenges. Though, personally, I'd prefer the Atma drop rate buff. >>
