This is based on yesterday’s discussion. I don’t agree with this change, I think it will cause excessive drops on some waves with many enemies. You need to let me know if you observe this in your challenge missions.
A better solution would be to limit the gifts and atoms individually, or (frankly the best solution), just leave it as-is. If some people want to waste their life testing out different kill orders in the off-chance that they might get a marginally better drop, then I see no reason to stop them
