#2 Allows a very clear divide between heels and babyfaces
While Hogan eventually became perhaps the greatest heel in history as a member of the nWo, the fact of the matter is that he is also the greatest babyface of all time. In fact, modern wrestling as we know it, as a global phenomenon only became a thing because Hulk Hogan championed it and took it to the next level. For a lot of kids who grew up watching him, Hogan will always be the babyface in colors red and yellow.
Ric Flair has been a babyface at certain points in his life, but he was always at his best as a heel, at all points in time. Charlotte Flair, who has followed in her footsteps, too only came into her own when she became a heel and left her babyface ways far behind her. It is clear that Hogan will be leading the babyfaces while Flair leads the heels into battle at Crown Jewel.
This is also clear from the fact that Seth Rollins is a beloved babyface and Randy Orton is a despised heel. The signs could not be any more obvious and I'm curious to see who the other members of both teams will be!
