-If we were to give relic equipment +2 that has not been augmented its own moogle slip, and we continued at the pace, we would eventually reach a point where storage slips themselves would begin to clutter a player's inventory. So we have to be very careful about the pace at which we implement storage slips to avoid creating so many slips that they become inventory hogs as well. With these thoughts in mind, we ultimately decided to limit it to upgraded pieces only
Except Storage slips hold more than 1 piece of gear. So rather than having 6 unaugmented AF2+2 pieces cluttering my inventory, I`d have 1 extra storage slip.
