#3. The restrictions
Jon Moxley was spot on when he said that 'Stone Cold' Steve Austin would never have been able to cut the "Austin 3:16" promo in today's environment. Today's WWE seemingly believes that restricting superstars and having them go for scripted promos are the way to go about things.
While many superstars aren't that strong on the mic, they don't seem to understand that the overly-scripted nature of promos only hampers their ability to grow. There are multiple superstars such as Seth Rollins, Roman Reigns and even Jon Moxley when he was there, who could easily go leaps and bounds when they're just given a few bullet points rather than a word-for-word promo.

It's not just the scripted promos but the general restrictive nature of the environment that makes WWE superstars unhappy. From social media etiquette to public appearances, superstars have a lot of Do's and Don'ts which may seem irrational to many, including themselves.
