Here's what I want...
A difficulty/ceiling score. Your routine is on paper, and a difficulty grade is assigned to each skill. Obviously a committee/group of people would be assigned to figuring out these difficulty scores, and yes, it would take a while to put them together, but I think once you got going, it is possible. Certain specific deductions are assigned to falls, busts, steps forward, early cradles, etc. and an omission earns you a deduction from your difficulty score (happens the same way in gymnastics.. miss a skill, and it's no longer in your difficulty score). There is still a subjective element of the score sheet there, left for each judge's preference on things like dance, choreography, flow of the routine, etc. however the lines are less blurry, as your score would generally be the same from competition to competition.
I think even something that simple, that may take a year or two to work out the fine details, will help greatly.
Also, just a question, are any judges at Worlds from other countries, or are they all representatives from the USA? If they are all from the USA, that's got to change. Look at figure skating, there are judges from multiple countries, and the judge from the country that the competitor is competing does not have a score counted towards the competitors score to avoid bias. I'm not going to get into my beliefs on the bias of the Worlds judges, because there are specific examples where the judges have favoured international teams (Bangkok, UPAC, Great Whites), but I'm saying, if the panel is all, or predominantly American, something needs to change there. Sure it'd be hard to find a Chinese judge educated on the American score sheet, but a Chinese judge may know cheer, and it wouldn't take long to teach them.
