#1.) To keep the rivalry going
One of the best ways to keep the rivalry going is by having a title change. While the days of immediate rematch clauses are over, WWE can keep this feud going up until the end of the year if they really want to. It certainly helps that Survivor Series is in between and they don’t need to have a match then, so if WWE really wants to keep it going until TLC, they can.
The best way to do this is by having Sasha Banks win the title.
