“It feels a lot different,” Rollins said. “I’m obviously in a very different place in my career to the last time I held a world heavyweight championship. I’ve grown so much as a performer, as a person, and my relationship with our audience has grown so much more.
“Everything in a lot of ways feels more effortless. I don’t mean that in terms of confidence or over-confidence, I actually mean it the opposite way in humility. I just feel like I can relate so much more to the audience’s plight and what they look for in a champion like myself and there’s just a great synergy there. It’s a smooth relationship now. It feels good on both ends and so happy to be the person I am today with the title I have.”

Wrestlers like Finn Balor and AJ Styles have also been elevated to the main event status once again after the introduction of the new World title. There are rumours that Drew McIntyre would be back soon to win the new title and find himself on the main event picture once again. In less than 1 month time, the new World Heavyweight Championship did an excellent job.
