I'm in the gritty editing stage and am second-guessing my character's voice and flaw. My earlier drafts had the MC with a over-confident, opinionated voice with two flaws: unable to stand up to authority figures and unable to ask for help from those he feels superior to. The potential problems with this is that I might be trying to juggle too many flaw/arcs and I should simplify and pick one. If so, which one?
One solution idea is to make the world more harsh. The character isn't the one with the problem, the world's just messed up and the MC can't fit in.
The world has a medieval fantasy flair and I could corrupt it further to make it more oppressive to my main character, who is a rabbit. Maybe make all the talking animals subservient to the humans so the beginning is a more Harry Potter in the closet, or a day in the life of District 12 (
Hunger Games). This rewritten version wouldn't have so much of a character with a flaw and an arc. He would probably have less of a voice too, since it would be more of a "common guy changes the world" story.
The reason I'm rethinking my character voice and flaw is because I've realized that my opening chapters are not a stasis=death (I've been reading
Save the Cat writes a Novel). I think there's more I can do to drive up the tension and urgency to make it stronger before the inciting incident (my MC, a rabbit, is an animal companion to a human girl who disappears).

I plan on reading a bunch of MG books to get an idea of some published "solution options" to my question, (maybe the fantasy genre leans toward more "save the world" narratives?) but I was hoping to get some help from the writing community too:
Would you/your MG children/your MG readers prefer a story about a character that...
...learns how to solve an important question we have about growing up in an surface-idyllic* world?
OR
...suffers in an unfair world of harsh rules and fights to set things right?*kidnapping children for magic experiments (similar to The Golden Compass).
Thank you for any thoughts/opinions you have on this topic!

PS. Let me know of any recent MG books I should look at as I research. Thanks!
