You might have a point if most of the biggest stars nowadays for the WWE weren't ancient part timers as well.
Seriously, who was the last superstar they made that actually sustained it? ****ing Cena? Guys like Reigns, Rollins, Strowman, Styles, and Bryan were either failures from the get go or sputtered out.
The closest they've got right now is Becky Lynch, and they had to be drug on their hands and feet kicking and screaming to get it this far.
Like I said earlier, they'd better get their shit straightened out before they move to FOX or they'll be dead on arrival.
