#1 Roman Reigns

Who will disagree to this?
Vince McMahon wants Roman Reigns to become the next face of WWE. The former is searching for a replacement for Cena which is considered next to impossible. However, the WWE Universe has grown a resentment towards Reigns due to the immense push he is receiving. The Shield Reunion has brought him back to the limelight, but this doesn't seem to last longer as it's clearly visible that WWE wants to push him as a singles star. Reigns main-eventing Wrestlemania 34 against Brock Lesnar for the WWE Universal Championship is a hot rumor and it would not work well for a babyface Reigns.
Reigns's recent feud with Cena proved his lack of mic skills; he received a backlash from fans and critics alike for his promos where he tried to defame Cena. After the feud, it had been noticed that there was an improvement in his mic skills.
Reigns needs to turn heel or else the crowd will boo him out of the arena. In 2018, turning heel should top his bucket list.
