For the past 2 weeks I came back to FF14 with the intention of actually proving a point in regards to how again the Atma drops are way incredibly low for what they should be and here is my prove:

05/30/14-Returned to FF14 for the sole purpose of grinding Atmas from fates and consistantly grinded for 10 hours a day on my own time off from work from 05/30/14 to 06/14/14. Within the first 6 days I earned the achievement Destiny's Child (3000 Fates) and Let the Bodies Hit the Floor (100000 mobs killed) on the 06/07/14. As of Friday, 06/14/14, I have currently have only 2 Atmas, Atma from Outer Noscea and Central Shroud with my Summoner full Ilvl 90 gear and the proper weapon equipped the entire time.
