Hi! The rewards and features added are known by the developing team prior to it being added. They are sometimes adjusted based on what the developers feel needs balancing. However, just because something is adjusted, it does not correlate that it is because the community likes or talked about the event/feature and it is being "nerfed" as that is counter intuitive. For example, it is possible that some change could have been planned prior and would have happened whether people talked about it or not.

Player's feedback is crucial of course because it could sometimes help in changing or suggesting a different approach for the team to forward to the developers (maybe even altering or stopping a planned change, which has happened in a number of occasions). Sometimes the event/feature are kept the way it or brought back due to player feedback.

Hopefully this helps, as you guys should not hesitate to let us know you like the event or have positive feelings about it. It really does help us. As the community's feelings about the event is stronger and more persuasive than just say for example my own opinion about it. So I do recommend giving us your feedback whether positive or negative; constructive suggestions and criticisms help. You c*so private message me or anyone in the team, if you guys ever have any questions =]

Hi! I just checked and the Edo Jinchuriki Fragments are still in Survival Trial as rewards. The fragments are random and that means you are not always guaranteed a specific fragment.

I understand the skepticism some players may have, but the rates have not changed. The updated survival trial rewards are still available but it is random.
