Rather than giving raw science Mix.r s should cost raw science to start (this adding a risk factor to them as you could lose raw science) and should then give you rare resources as a reward for completing it. I have asked many people who agree with this including the streamer MaxFox_Gaming.

they might add that along with raw science as a reward, but for now i think it will remain as another method of earning raw science outside of quests.  and since it's supposed to be a collector for raw science, were would the rare resources even be coming from? and what would you classify as a rare material? i would prefer that anything that would drop from a boss not be a reward from the mix.r.
