#1 The success of Sasha Banks and Bayley's WWE women's tag title reign
WWE already has a tag team championship floating across RAW and SmackDown, one which has proven to be a tremendous success. The booking of the Women's tag team championship since WrestleMania has put the men's tag titles to shame. The reign of Sasha Banks and Bayley has shown that a single title can work.
WWE should follow their own model and have only one set of men's tag team championships, even if it is only to make it equal to the women's version. But it goes beyond that, as the now-former best friends enjoyed a successful run as tag team champions.
They took advantage of this rule to dominate RAW and SmackDown, eventually becoming the most entertaining act in all of WWE. Unifying the tag team titles would elevate not only the champions but also the belts they are holding. Banks and Bayley defended their titles all over the place, boosting the prestige of the titles.
WWE has found the blueprint on how to ensure a tag team championship reign is successful during the brand split - and with limited teams on either show. They must now implement it on the men's titles. The collective talent on RAW and SmackDown would ensure it works wonders.
