The problem isn't that it isn't random its that there isn't a system in place to safeguard against horrible rng luck. It's just simply not fair watching someone get 12 atmas in 4 hours while another person spends 60+ hours without one atma. I think SE just writes this off as "more than likely won't ever happen" but it happens way to often. They need a system that scales back rng over time when luck doesn't go your your way. Whether it's atma farming, hunts(logs), materia melding, or coil drops. Seems like every aspect of this game is designed around some type of RNG system which is starting to test the patience of even the most hardcore players. I really hope SE stops designing so much content that is relies heavily around RNG.
