Yeah, for action animes, that's a good excuse for power up. Just look at Saint Seiya. That anime has no sense at all, everytime they are about to be defeated, their relationships remind them that their resolve outmatches everything and suddendly they become Super Saiyan 3000.

Seiya: I'm about to die.

His friends: But what about our promise?

Seiya: Oh, right! I can't die! *Defeats the bad guy with an epic move*

Basically, in action anime, the relationships make the story more interesting. Just like Miles and Kerry said once: It really means something. For example: When Jaune finds what his semblance is, it has to be during a fight when he watches his friends (Or Pyrrha) about to be killed and then he unleashes his semblance which turns out to be a great advance against his current enemy.
