This is going to be a very long post, but I hope you'll bear with me. I sincerely hope someone on the 14 development team reads this and understands that I am frustrated, and I don't want to be, and they need to more closely consider how the players are going to feel about the content they develop.
TL;DR: Atma grind is incredibly variable on how long it takes, which is frustrating when doing with other people and they finish twice as fast as you. Please take the "luck" factor out of it. I would like the FFXIV devs to reconsider the extremes they implement content at. Don't just be 0 or 100, find the middle ground.
I started playing the game back in Shadowbringers. I tried to keep up with the relics, so when the one-time step to grind fates in Stormblood zones came out - half in the near east and half in the far east - I was able to start on it right away. I started with my FC at the time, about 5 of us counting myself. By the end of the day, the others had finished the step, while I was only half way through. The next day, I continued the grind with my girlfriend at the time. She was starting fresh. By the end of the day, she had finished. I still wasn't done. I finally finished on the third day.
Fast forward to current times. Time for the new field operation, and new relics with it. Naturally, the first day of the new content, I'm there in the field operation. My boyfriend and I start pretty early, we unlock it, grab our relic quest, and get in there. It's pretty fun, honestly. And then after about 7 hours, I see a pop-up: my first demiatma. I had forgotten about them until then. I told my bf and asked how many he had; he had 5. I sort of laughed at the time; I mentioned it was funny how horrible his luck usually is, it's good that he's finally lucky at something. I only considered how mildly annoying it was that I was so far behind until later, when I didn't end up getting a second that day.
Day 2: we start FATE farming. We realize since the atmas each only have 2 or 3 locations they drop from in OC, it would be more efficient to be guaranteed the ones we need and not overcap. We spend all day farming. We have raid at 9, but once we finish at midnight we continue FATEs. He finishes getting all his atmas that night. I'm not even half way done. A little frustrated, but surely I'll finish tomorrow, right?
