If I have my way I would like to experiment a few ideas to tidy up the badminton rules. 1) First one is to deal the annoying antics of some players raising their hands to indicate that they are not ready to receive service. Let’s have a fixed time, say 10 seconds, for both the server and receiver to get ready and, say 3 seconds afterward to deliver the service. The main point is both players get 10s to prepare, and to serve/receive within the 3s period after that. During the 10s period the players can do whatever they wanted, within reasons. They can have a quick drink; talk to their double partner (not coach, I will get to that later) or change racket etc. And they have the right to serve within the next 3s, even their opponents turn their backs! Obviously the 10/3 seconds is just a number that can be adjusted. May be a red/green LCD panel by the umpire’s chair to remind them when to serve. 2) I would also propose to introduce a time out, say 30 seconds, per game for each side in addition of the mid game interval. Both sides can exercise the TO anytime during the game, like the mid game interval the players are allowed to consult their coaches during the TO. Apart from the mid game interval and the time out there will be no more unscheduled tower breaks, mopping of floor etc. Hopefully this will eliminate or reduce the tactical time wasting some players employed especially during the crucial time of the match. 3) About the silly thing that one player likes to change the shuttlecock and the other doesn’t. One option is only the server can decide to change the shuttlecock or not. If the other doesn’t like it, win the next point then it will be your chance. The other option is to have a ‘new’ shuttlecock for every point. After every rally you get a new one from the service judge and all the ‘used’ ones will be examined later. If they are good as new they will be the ‘new’ shuttlecocks for the next game. Personally I prefer option 1 but option 2 should be do-able at least from QF onward. 4) The Laws of Badminton 9.1.5 The whole shuttle shall be below the server's waist at the instant of being hit by the server's racket. The waist shall be considered to be an imaginary line round the body, level with the lowest part of the server's bottom rib; I will get rid of this unenforceable rule that based on an imaginary line nobody can see but can only guess, including the service judge. Unlike a bad line call, the service judge can make a bad decision based on his/her guesstimate (biased or not) that nobody can challenge and even the umpire cannot overrule. I will just have a simple rule that the server's racket at the instant of hitting the shuttle shall be pointing in a downward direction. If someone developed a serve that the point of impact is about head height, so be it. As long as the same rule that apply to all, you have to deal with all kind of shots during a rally anyway.
