Yes the FATE + RNG combo indeed sucks but dont let it get you down, just endure and you will eventually get all of them. To me it seems that Atma part is there to test your luck, determination and patience, its kinda like a mindgame where it tries to get in your head and mentally brake you. Personally im still running T2 for tank earrings after farming it for 4 months, same goes with T1 tank neck as those just do not like to drop but i refuse to giveup at this point.
