You guys ever thought Badminton service should be like Volleyball or Tennis?
That is, from behind the back line (maybe 2nd line for women/amateurs) and can be as high as you want.
I think it will make the game simpler with no service judge and encourage beginners to move and learn clears/smash properly. I see so many early beginners playing each other barely breaking a sweat because they don’t hit hard and don’t chase after the shuttlecock. At least if you start at the back you’ll need that initial run to the front and will be forced to hit with some power.
