The problem with the Jaune's "imposter syndrome" arc is that he is, in fact, an imposter
Jaune faked all of his papers and exams to enter Beacon Academy, making one of the main characters of the show a liar and a fraud.
Now this wound't be a problem if it was shown that he feels guilty over this, or that he had altruist reasons to want to become a huntsman.
Take Leorio from Hunter x Hunter as an example: he is a fraud that is hard carried by his friends throught the whole hunter exam, but we fell sympath for him because he wants to become a hunter to help people, and he is risking his life for a good cause despite being weak.
In Jaune's case, however, he wants to become a huntsman for his own personal dreams of glory and becoming a hero, and he risks people life in the first season because he is dumb and unprepared for danger.
He also don't show that he fells guilty for cheating, but rather that he is having a hard time in the academy for being weak. Again, it's all about him, not the others.
This is the reason why i don't like Jaune as a character: he does almost nothing for himself during the first 3 volumes and causes problems all the time, but the show always rewards him for that.
