Listen to many longtime fans of WWE, and you'll be met with same criticisms time and time again. For a lot of older enthusiasts, the promotion has lost it's way, becoming a pale imitation of the glory days of old. In fairness, it poses a bit of a dilemma for Vince McMahon and company, who simply can't return some of the nuances which excited fans over the years. For one example, blood can't come back, at least not at the moment. It goes against everything this current, child-friendly World Wrestling Entertainment stands for. Needless to say, if WWE were to start presenting claret on television regularly, there would be a real backlash from sponsors. Similarly, the WWE Divas won't go back to wearing skimpy outfits anytime soon. Sure, this rule has loosened somewhat over the past few years, but it's not quite as flesh-baring as it was during the Attitude Era. What are WWE to do? Allowing the women of the company to wear precious little clothing would again anger investors. Instead, this list stares beyond blood and sex, looking at things WWE have no excuses for not doing in 2015. The product is generally accepted as being stale, and has been for years, but what's stopping McMahon from making these changes, ones that would arguably reinvigorate proceedings?
