So here's a question: If we were another team, would we actually bother getting seals from the proctors, or would we just steal seals instead from then-weakened teams?
...Wouldn't everyone do that, thus making for relatively-few actual seals in the place?
You're probably going to spend more of your chakra in a fight then you will activating some seals from the proctors.
But I really do hope the QMs remember that every team we're fighting has probably activated proctor-seals and fought at least a few battles, and chakra only regenerates over a 24 hour period. Except for the ones who also have a barrel-buddy, they aren't going to be coming at us full.
