My best explanation is just that unregulated fights are against the rules in hunter academies because of how easily they could get out of hand.

It's okay for them to spar in an arena during a class exercise, of course, because

1. It's completely regulated. There's a teacher there to monitor their Aura levels and stop the spar once someone gets low.

2. The combatants are fighting as a training exercise, not out of some kind of personal problem.

In an unregulated fight, no one's monitoring the students' Aura, and when people fight out of anger from some personal problem or grudge, some people are liable to take things too far and just keep going. In this situation, someone can actually get hurt.
