they need a better system that beat RNG system for loot like Atma or Alexandrite from FATE

because using True RNG system doesn't 100% provide progression for some(a lot of) playersk.

Suggestion: Increase the drop rate by 1% every failure to obtain the loot so if unlucky people keep working on it, they'll eventually get their reward.

The problem with the current system is that the true RNG system is not a good practice for games that supposed to make you feel rewarding as you progress.
