I agree with this. I always thought that Alloy Plates were common and Polymer Bundles uncommon. It states that Alloy Plates are uncommon but they're an exception because they drop in quantities like common resources. I think it'd just be easier to place them in the common category instead. Vice versa for polymer bundles.
Alloy Plates are beyond common. I have 486k of those things. In fact, the foundry requirements should be changed. Too many things use obscene levels of Ferrite or Polymer Bundles. Barely anything uses 3k Alloy. Take any recipe that uses Ferrite, make it use double the Alloy Plate cost. I'll be fine. I'll just do another Void run if I need a another 10k Alloy
