#4 Shock factor
Royal Rumble is known for shocking the fans. Each year, Superstars from the past return to WWE and entertain the audience. A few wrestlers have also made their debut through this pay-per-view. Ronda Rousey, for instance, was one of the biggest Superstars to debut this decade at Royal Rumble.
But why should surprises be limited to just the traditional battle royal match when WWE can shock the fans through other matches as well. We know that the predictability factor doesn’t usually work during Brock Lesnar matches. Vince McMahon personally takes care of The Beast Incarnate’s booking and ensures everything will happen as he expects.
Cain Velasquez and Brock Lesnar is a match that can have wonderful surprises if booked correctly. Who knows? Velasquez might even defeat Lesnar for the WWE Championship. It would be a huge surprise for the WWE Universe watching the show.
