One thing that is refreshing to see in WWE is the fact that superstars have a greater amount of freedom when cutting promos on the mic. This started probably right after WrestleMania this year, so the credit for this cannot be taken by Paul Heyman.
As an example, Dolph Ziggler made a subtle remark about the performance of Goldberg during MizTV on the July 15 episode of Raw. This is very encouraging to see. Thankfully we are out of the era of totally scripted promos that feel completely forced and inauthentic (remember the 2015 Roman Reigns train wreck of a promo where he made a reference to Jack and the Beanstalk).
WWE is instead allowing superstars to call audibles in the middle of promos, much like Peyton Manning or Tom Brady at the line of scrimmage.
