Does the endgame become gambling on high rarity parts that otherwise get recycled into another chance of becoming high quality because rng?
I don't like it, and I play gacha games. Hopefully this can be turned off. The module is fine, no need to change it for the sake of change.
I get how the whole "RNG" feels strange at first, but in practice you're mostly not producing single units of anything, rather mass quantities. So in the end it's really just a statistic rather than hoping for something to drop individually.
