Dude, you seem to be under the impression that Lint's balance breaker increase her base stats. It really doesn't and more angel power? The number of wings are irrelevant dude. They are mainly for rank. Micheal for example has 12 wings and yet Dulio stronger than him despite having 10 wings.

Lint uses her Balance Breaker in Life 5 during the second half of the Vali vs Rias match ans despite that she still couldn't beat Sha Wujing. You say you want to wait for the translation and yet you're already aware that Lint reached Balance Breaker so obviously she used it in her match against Sha Wujing. For Akeno, despite her holy lightning she still didn't win.

I know that Asia was able to maintain her Balance Breaker during the time she assisted Grayfia against Artemis and I'm sure that battle lasted a while since they were fighting a god.

Rias knows can't defend herself so her only solution is hiding her. Up until now Rias faced weak team so Valerie was safe.
