TL;DR
A negative quality probability on an assembler has a chance to decrease quality on craftWhat?
Slight tangent, it would be nice for any machine with a negative quality rating (say, from speed modules) to have a chance of decreasing the quality of the output item, with the same rules as normal quality. This would be a way to decrease quality of unwanted items, as well as a counterbalance to increasing the quality of base resources (plates, plastic, etc) to then craft with them normally. I could also see this being used in modsWhy?
As of now, there is no official way to reduce the quality level of an item. There is also no penalty to the negative quality bonus beyond 0%. This would change that. Even if it was a mod-only feature, it would be very useful for mods that interact with quality in new and unique ways.On second note, how about that negative productivity bonus... but people might riot if you implement that feature
