A lot of people point out that it doesn’t make any sense that Harry and Ron didn’t like their schoolwork. Well I figured out why:
It’s because the magic system is just as boring in-universe as out of universe. It doesn’t make any sense in universe either. Harry and Ron realised Rowling’s magic system kinda stinks way before we did, because they spent all day learning it.
If Sanderson had been writing Harry Potter, then Harry and Ron would have liked learning magic as much as Hermione did (Also, Sanderson actually DID write a book about a super-school, it’s called Skyward, it’s good)
Ok the ghosts coming out of the wands thing kinda came out of nowhere, but all they did was tell Harry to run away. It’s not like they had a massive impact on the fight.
