Sacred gears have the potential to grow and evolve with their wielders. Take night reflector for example, it wasn't a very unique or powerful sacred gear but the wielder was shown to be able to create powerful armor similar to Issei's dragon armor.

I can't remember which volume he stated that in. Was it before or after Asia created the barrier than was capable of blocking the attack of a super devil?

I agree with you, Asia needs to amp up her skills if she's going to not be a liability to her team but I don't think she's a complete waste. Characters have shown capable of boosting their powers and abilities through their desire and will to achieve. If she wants to become stronger, she's going to have to learn how to create powerful balance breakers with her sacred gear. My suggesstion is she figures out a way to use Fafnir's power without having to summon him as a familiar. In my opinion, she should do a Regulus Nemea and learn how to create powerful dragon armor, not really using it for combat but to protect herself or better yet she could learn how to utilize fafnir's treasure summoning abilities or curses.

How about she learns how to create a curse dragon armor that relies on fafnir being sealed in her sacred gear therefore fafnir would be able to use powerful curses on her opponents and she could focus on healing her allies or protecting them with her barriers. Koneko was able to seal a evil dragon in one of issei's jewels, Azazel was able to seal fafnir inside a spear so it's not completely out of the real of possibilities.
