Disagree. Most sports are arbitrary; quidditch is most definitely poorly designed. Tennis scoring makes sense, it’s just unartfully counted.
Quiddich was created by someone that obviously never played sports in her life. Calvinball is a better thought out game.
But if people want to run around playing a muggleized version of a game that omits the best part (flying) eh who am I to stop them?
Just wear shiny yellow clothes and tell the authorities about all the bad things you think anyone has done. 
I couldn’t write a successful series of fiction books, but…
I’m very bad at sports, and very bad at strategy, and yet I could certainly invent a better sport.
But she made the big bucks because she got a whole bunch of other stuff right, even though the Quidditch part doesn’t work.
I was under the impression that tennis point scoring goes 15 -> 30 -> 40 just because tennis GAME scoring goes 1 -> 2 -> 3 -> 4 -> 5 -> 6, and they wanted to avoid ambiguity or confusion. Not that it’s necessarily the best possible, just that I think it’s not stupid.
Tour de France, surely.
Not sure why they need the broomsticks. Seems to me charging around a pitch trying to get balls through tiny hoops while being bombarded by missiles is tough enough without potentially getting your nuts twisted.
This is true. The kicker is the snitch gets to run around wherever they want to around the general area of the game before eventually coming to the pitch at the end of the game. And he has no broom…that’s a huge help. I was the snitch a time or two in practice and it’s frigging exhausing.
Verisimilitude
In a crazy turn of coincidences, here is a very good article on The Ringer about the sport.
J.K. Rowling said she invented Quidditch after a fight with her boyfriend, in order to “infuriate men.” Specifically the snitch being so valuable. So it’s one of the biggest & longest lasting cases of trolling of all time.
You know, intentionally distorting the description of a game hurts your point, it doesn’t help it. A tennis game is played to 4 points. The points are named 0, 15, 30, 40, & game. It would be exactly the same game if they called them 0, 1, 2, 3, & 4, or Pickaxe, Lungwort, Periwinkle, Silkworm, & Asparagus. It doesn’t have the inherent imbalance that Quidditch does.
I read that as how satisfying it is that the game infuriates men “given [her] state of mind when [she] invented it.” That is, having been invented right after a row with her boyfriend.
I think the weird rules and scoring are because she needed some mechanism where a new player with natural talent could instantly be the star of the team without having to spend half the books describing quidditch games.
