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
Reading Enders Game after reading the Harry Potter series felt like those were two opposite ends of the spectrum.
Harry was special because fate made him special and all things revolved around him regardless of his actions.
Ender was special because the author said he was the smartest kid in the room and all things he did worked because if it didn’t work, then he wouldn’t be the smartest.
It should be worth 5 points (half a goal, so it functions as a tiebreaker), but still end the game when caught. That way, the team in the lead is trying to catch it, and the team that's behind is trying to prevent the opposing seeker from catching it to buy time to close the gap. It's still important that way, you can't win the game without it, but the rest of the team is also contributing.
Plus, when there are positions on the team whose entire goal it is to beat the shit out of the other team, it makes sense that you'd want to split their focus between scoring points or ending the game. As-is, there's no reason a beater should be trying to do anything other than beat the shit out of the opposing seeker.
Fun Fact: In California, a frog that dies in a frog jumping contest cannot legally be eaten. It, and this is from the state code verbatim, "must be destroyed immediately".
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
That was my take when watching the movies (never read the books). I figured the snitch was near to impossible but Harry just had main character syndrome, being able to actually see the snitch.
Yeah harry is just cracked at the game for no particular reason (never even flew before he went to Hogwarts)... they allude to some quidditch games lasting days, at which point 150 points isn't a big deal anymore.
Another option would be to add other win conditions, like the game automatically ends after an hour. That would add some strategy too- if your team is up and the clock is starting to run down, you could devote a couple players to blocking the other teams seeker. But you would have to be careful because then the other team would have an advantage scoring goals, and could sneak back into the game that way. With a few minutes left, unless the score was very close, the game would turn into a mad scramble for the snitch since that would be the only way to make up the score difference, with maybe just a couple people playing defense to keep the other team from getting free goals.
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.
It's not an instant win. It's already 150 points and an instant end to the game. It usually happens that whoever catches the snitch wins, but not always. See: Quidditch world cup in Book 4 of the series.
It's technically not an instant win, just a ton of points and an instant end to the game. In a lopsided enough match a team could catch it and still lose.
