Shinigami can be pretty stubborn at times, and quite a few of them got beat up badly in fake Karakura, but still never used their Bankai. Refraining from doing so, probably impaired their Reiatsu level equivalent to what the limiters would have done, had they not been deactivated. That's Shinigami logic for you...
