#3 An Opportunity for All

The free-for-all structure will offer the chance to appear on the rival brand to everybody. This will carry stakes, and the audience will have another reason to watch the show every week - everyone from Seth Rollins to Sin Cara gets the opportunity to work for the chance to qualify. Of course, it is necessary to not allow the same superstars to make the jump every single week, since that would turn the viewers away, thus proving to be counter-productive.
Based on last week, it is clear how the rule can benefit certain wrestlers - Kofi Kingston started his WWE Championship defense against Daniel Bryan on RAW, and followed it up with another successful venture against Styles and Sami Zayn on the very next night. It built credibility for Kingston, who is currently viewed as a fighting champion, in line with his resilient babyface character.

With specific goals in mind, this rule can be used effectively to showcase the skills of the younger superstars on the roster - names like Chad Gable, Ricochet and Ali should move around and establish themselves as legitimate stars in the eyes of the WWE Universe, opening the doors for them to eventually challenge for the bigger titles in the company after building an organic connection with the fans.
