#7 Should not retire - Brock Lesnar

Whether you love him or hate him, Brock Lesnar still manages to have a dominating presence like no one else, every time he appears on the screen. While having a part-time wrestler as the Universal Champion was probably not the best idea, now that he is not the Champion anymore, an occasional appearance from The Beast Incarnate has the ability to shake things up quite well.
Take Hell in a Cell for example, Lesnar's shock appearance saved WWE from having to end with either a title change or a clean loss for Strowman. Yet another feud with Reigns and Strowman does not seem like it has much to offer, and WWE would do well to end the same at the Crown Jewel event and have The Beast Incarnate move on to a fresh feud.
It is highly unlikely that Lesnar will return full time to the company in the future, but an on-off appearance between UFC fights will work quite well to keep the audience invested.
