RNG is still luck no matter how you slice it. Saying people want something for nothing is just a hyperbole; people who are against the Atma grind have complained, but many others also gave ideas on how to make it better while still requiring a lot of work to be put in. You cannot do FATE farming wrong; you grind the same ones at the same rate over and over again and either get lucky or you don't. You can do just a few day and get lucky or don't. That's the nature of RNG. Do the same FATEs 500 times a day or do them just 40 times in a day, it's still up to luck to decide whether or not you get the drop.

People that insist that the grind for Atma is not bad and that people should stop whining are simply refusing to see problems from the other side or lack the ability to understand.
