It is the same for all kinds of tablets and degrees and we think it is actually much better than before. Instead of having around 6-7 different degrees of elements, you have only 1 or maybe 2 different degrees of elements in your storage. And btw, if you collect alchemy materials, they give you only 1 degree of elements too. If you have an alchemy material and rondo it, you will get only 7D elements.
But all kinds of it. So you will get a certain ammount of Fire 7, Water 7, Earth 7 and Wind 7, but no 6D or lower elements from this material. With this system it is a lot easier to get the elements required for your tablets and your storage will not be filled with like 50 different kinds of elements.
