Since the three groups had fought and killed the Rank 3 Grisly Bear, when they didn't even have Rank 3 Warriors in their ranks, they were deemed to have done a great act.
In a place like Navita military deeds were extremely evaluated, and especially when one managed to work wonders, and bring unexpected results.
For example, if Roy hadn't taken care of that Rank 3 Grisly Bear, then he would have stormed the other teams, and they would have end up suffering casualties as well.
That would be the best scenario, because since the strength of a beast was above that of a Warrior of the same Rank, then even with a Rank 3 Warrior these guys would have suffered losses.
But there was no Rank 3 Warrior in these three teams, so even if the Rank 3 Grisly Bear was wounded, he might have wiped out the three teams altogether.
