Just as the title says. Does anyone have an incling of an idea why we have 5 seperate grades for items that do the same thing and costs the same amount to make? There's really no reason to have different crades of these things, as they all need exactly the same mats, and really does the same thing. Just having 1 of each crafters prism would work just as well, and be less bloated and complicated.

My theory is that they originally planned it to work in a different way than they do now, but changed their minds for some reason and just let it be implemented half-finished.
