I hear what you are saying, but - just because cores aren't as abundant as glimmer doesn't meat they are omitted from being in the economy. - although there is an either or scenario (infuse with glimmer or infuse with cores) 90 % of the time they are required to progress, and is a resource that should be carefully managed. none the less its semantics, and its not worth having an argument over. to me? its like buying a donkey with diamonds really. - the purpose is completely missed and requires a re work. i would grind for additional ways to earn cores none the less, if it's implemented properly and executed where the purpose of the cores can benefit the player and not used as a tool or a means to chase the illusion of light.
