#3 Wins and losses must matter
Now this doesn't mean that WWE has to go all-in with a win/loss record like AEW is reportedly planning on doing, but they cannot continue to go forward with their 50/50 booking style.
Even though Vince McMahon views WWE as sports-entertainment, the reality is that the majority of his audience views his company as a sport where the match is the most important element.
During the Attitude Era, Vince McMahon and WWE were incredible at making every main event level character seem like a legit contender to be the top man in the company, so they're clearly capable of creating a roster full of wrestlers who are over.
Even though a strong character can make up for a lot for any Superstar, it's pretty hard for even the strongest of characters to have to find an excuse for losing at least 50 percent of their matches.
