#1 To get as many people involved as possible

This is perhaps the best possible thing that we believe the WWE 24/7 championship will achieve. Sure, will it be a comedy title? Yes. Will it be passed around freely and held by many different superstars? Yes.

Will it get underutilized superstars on the card? Yes! That's the best thing that it can do, because there is a roster full of talented superstars who simply don't get a spot on the card. Instead of sitting in catering, it allows them to actually compete for a title and be a part of an interesting storyline.
The truth is that titles aren't what matter most to superstars. It's a consistent creative direction and being actively involved in good storylines. The 24/7 title, since it involves so many people, can lead to some solid storylines down the road, even if they're light-hearted in nature.
