I want materials to have better HQ conversion rates, because they lag WAY behind final products.
However, I really don't want to be touching up materials. It essentially doubles the synth times.

They should throw us a bone and keep mats quick to make, with better HQ conversion rates.

I'm pretty sure your chances of getting a HQ of a material is equal to your chances of getting HQ of a final product right off the synth, without any touchups. And that just doesn't make any sense.
