#4 The imbalance between SmackDown and RAW
Ever since SmackDown received the backing of FOX, it has been a much bigger deal. It has also eclipsed WWE’s original flagship show in RAW, which is also the world's longest-running weekly episodic TV show.
The difference between the two shows at present is basically night and day. SmackDown boasts better viewership numbers, sponsorships, and reach and is on another planet compared to its red counterpart.

This is very similar to the time before the brand split, and it is a route Vince McMahon and company may be thinking of going down.
#3 There are superstars currently spinning their wheels
Despite two shows and a trimmed roster after many releases, WWE still cannot give everyone worthwhile storylines. If you are getting deja vu from this sentence, it’s because this scenario has played out before.
Heading into WrestleMania season, there are many superstars who have little direction. This is in stark contrast to the initial years of the brand split, where there were more wrestlers in the spotlight.
As the situation has gotten progressively worse over the years, the company may be thinking of switching things up and ending the brand split. Now that they have a smaller roster, they could do a better job of managing it and make amends for the past. They could have more serious contenders for their championships as well.
