#7 AJ Styles: babyface turn
AJ Styles is having a championship run that almost mirrors that of Seth Rollins, from 2015. While both Rollins and Styles are tremendous talents, they are being asked to do things as champions, which makes them appear somewhat weaker than normal. For example, Styles losing all of those matches against James Ellsworth. Sure, some may find Ellsworth, and the story surrounding him to be entertaining, but his success is coming, partially at the expense of the WWE World Champion.
Another factor to consider is that Styles has a huge following of dedicated fans, who will support him regardless of the storyline he's involved in. With that said, AJ has always performed better as a babyface. It's simply the way he is. In his normal, day-to-day life, AJ Styles is one of the most humble people you'll meet. At the end of the day, it just makes better sense to have Styles as a fan favourite.
