3. Break away from the Elite
When it comes to pro-wrestling a stable serves several functions.
For one, it is a great storyline hook, especially for heels (which is why most stables are either bad guys or end up that way). This is because the numbers game can be used to turn the tables on babyface wrestlers and generate heat from the crowd.
Another reason for a stable is to elevate the performers in it by having them associate with a major star. This was attempted and succeeded with Barry Whindam in the Horseman, but attempted and failed with the NWO and Stevie Ray. Yet another reason for Stables has to do with merchandising.
However, Kenny Omega isn't being helped by the Elite, though they may be helped by him. He doesn't need a stable to generate heat, or to sell merchandise. His presence does elevate the lesser members of the stable, Like Marty Scurll and Adam Page, but Omega will truly shine on his own.
