I think it was just a contrivance to both make a sport for the books while also allowing the Main Character to automatically be the most important person all the time (like basically everything else in the books).
Yeah the truth is that Harry is more or less completely useless at anything other than quidditch in the books. He’s just a symbol that actually talented people rally around
Functionally, he’s good at being reliably moral. See: the mirror of erised, the second GoF task, going willingly to his death.
Reliably moral by traditional wizarding standards*. Hermione is more reliably moral by standards external to the wizarding world.
Hermione blackmailed a journalist and kept her in a jar for several weeks. The following year she cursed a fellow student and left them permanently disfigured. I’m not sure that I would consider her more reliably moral… a good person overall, but with flaws.
Goes well with the rest of the writing.
They need to up the intelligence on the snitch. Make it so hard to catch that it hardly ever happens. Seekers now spend most of their time as normal players, while keeping an eye out for the snitch, then darting away every once in a while for a catch attempt
Another way to balance would be to simply make it not an instant win. Instead it’s just worth a large amount of points, but the other team could still win if they score enough before the game ends.
