WWE is gearing up for the upcoming premium live event, Survivor Series: WarGames. The event will take place in San Diego, California, on November 29. Multiple matches were confirmed for the show on the latest episode of Monday Night RAW.One of them will see John Cena defending the Intercontinental Championship against the former champion, Dominik Mysterio. The King of Luchadores interrupted Cena during his last RAW appearance, demanding a rematch. The GOAT was ready to defend the title in Madison Square Garden, but Mysterio challenged him for a match at Survivor Series: WarGames, which takes place in his hometown.The Last Real Champion accepted the challenge, as the rematch between Cena and Dominik has been made official for the upcoming spectacle. That said, while there is nothing inherently wrong with another John Cena vs. Dominik Mysterio match, Triple H has missed out on a major opportunity by booking it.As the name suggests, the major attraction for the upcoming PLE is the WarGames Match. It is a five-on-five bout that takes place in a dual-ring setup surrounded by a steel cage. This year, on the men's side, Team CM Punk is set to face Team Vision. The latest episode of RAW has seemingly confirmed the lineup for both sides following the returns of Roman Reigns and Brock Lesnar.The Beast Incarnate was last seen at WWE Wrestlepalooza, where he squashed John Cena. Given the one-sided nature of the bout, many believe Cena needed to redeem the loss against Lesnar to conclude the rivalry. The upcoming WarGames Match provided a perfect opportunity to have Cena and Lesnar lock horns again.Moreover, after a brief encounter at WWE Night of Champions, there is still unfinished business between Cena and The Vision, which could have been revisited if The GOAT had joined the babyface team for the Men's WarGames Match.After finally completing his Grand Slam quest by winning the Intercontinental Championship, John Cena could have checked another box in his illustrious career by competing in the WarGames Match before retiring. Choosing not to involve The GOAT in the five-on-five bout might be a mistake on Triple H's part.John Cena could become a WWE Hall of Famer next yearJohn Cena will compete in his final WWE match at Saturday Night's Main Event XLII on December 13. The winner of the Last Time is Now Tournament will face The Never Seen 17 in his last bout.That said, according to Bryan Alvarez of the Wrestling Observer Newsletter, The GOAT could headline next year's class of WWE Hall of Fame. If this happens, fans will see John Cena in the Stamford-based promotion just four months after his retirement match.
