I seriously hope those Sternritter won't be able to use those stolen Bankai to full potential.

Those Captains have trained with them for decades or even centuries. They shouldn't be something you can just take and immediately use at full capacity.

Actually I think it's stupid they can even be used after being stolen in the first place, rather than just being sealed up, since they are a part of the Shinigami, but that's already water below the bridge.
