I will restate my and many other peoples desire on this. Cores should be removed only from infusion. If cores return to only be used for Masterworking then no changes need to be made into how often and how many cores we are receiving currently from activities. In my opinion, the Core flow is Sufficient as it is now for one of the two, Masterworking OR Infusion. Not both. Adding more sources to grind for one core at a time is not a solution to keeping Cores for both systems. Removing cores from infusion will make masterwking relevant again, and possible for many more. That is my hill, and I so have chosen to die on it.
