That's exactly why the RNG-based Animus FATE grind is sub par Game design. It is not about a matter of skills or at least endurance. You can do it as often and long as you can, it is still possible that you get nothing in the end. Why SE does not answer to the complaints and has no plans to change anything for now is just beyond me. RNG is the worst thing to have when it is about one of the best weapons in the Game. Thanks God I was more lucky but I still think it should be changed. Good luck to your endavours, OP. May the ATMAS be with you.
