#1 Stopping the overly-scripted nature of programming

Perhaps the biggest detriment to WWE's programming in 2019 is the fact that it's very formulaic, predictable and overly-scripted, whether it's promos from superstars or the announcer's calls.
There's simply too much restriction and WWE probably feels that with the nature of their show, it's best to keep the overly-scripted nature of things. The issue with this is that it's extremely detrimental to performers and hampers their ability to grow.

As a result of this, we have seen multiple NXT prospects such as Apollo Crews flounder on the main roster. Even with Triple H in charge, it's simply unlikely that the nature of the overly-scripted program will go away.
Sure, certain performers may get leeway, but since the Performance Center is training the talent of the future, there's a high chance that they teach future superstars promos in a scripted manner rather than in an improvisational one.
It'll certainly be interesting to see.
