#4. Wildcard rule
On the 6th May edition of Monday Night RAW, Vince McMahon came out, followed by Roman Reigns (who announced he would be there). A returning Daniel Bryan followed and behind him was WWE Champion Kofi Kingston.
McMahon then decided that he would introduce something called a "Wildcard" rule, where three superstars from a given brand would be allowed to appear on the opposing brand. From the look of things, it'll be a weekly thing. This is basically the biggest indicator that WWE is planning to transition out of the brand split.

Lars Sullivan's confrontation with McMahon backstage led to the latter then changing the rule to four superstars instead of 3. Despite that, Elias too, appeared on RAW.
Every week, it looks like we'll be seeing a rotation of superstars appear on the other brands. It's a very unnecessary idea and it isn't going to benefit anyone.
