It honestly wouldn't be too much for them to implement a way to store the stat data or let it reset and be reallocated once withdrawn. I personally would rather them have a section in the Armoire as there isn't a limitation to the storage. As a FC Leader whom prefers to enable my FC Memebers to request crafts at either a major discount compared to MB prices or free(should we have the required materials) I already have max retainers which are full of every mat imaginable. Thus using a retainer for every class and every relic available takes up a lot of space.
