#1 Dominick

It's no secret that Dominick Mysterio is being primed for a future in the WWE and while that career path seems like a done deal, Rey Mysterio exiting the company could stall it. It could result in Dominick being directionless and not give the WWE Universe a satisfying ending to an amazing storyline
WWE could just redirect focus to Dominick, Aleister Black and Austin Theory versus Rollins's cult, but it wouldn't have the same meaning to it without Rey Mysterio. Furthermore, it wouldn't showcase the struggle that the Mysterio family is facing right now between staying safe and defending the family's honor.
Look who just shut down all of Tony Khan's critics! More HERE.
In all honesty, this storyline is white hot right now and is about as personal as something can get in today's WWE. It is also the ultimate showcase of what Dominick can do in the future, which is why it would be be a huge blow to the young man's future in WWE if his father were to suddenly vanish from television.
