#1 He thinks the pay off might be bigger for WrestleMania

While it is true that having the pay off for Kingston's journey end up at WrestleMania 35, the way to get there has been full of convoluted storytelling and downright mean tricks.
Bryan was more so thwarted by members of the Authority as he attempted to gain the respect from everyone in WWE that he was a main-event guy.
While constantly keeping him down will only make his eventual rise all the more sweeter, the hoops that Kingston has had to jump through just seem like the machinations of a mean old man.
He's dangling that carrot in front of Kingston's mouth constantly only for him to yank it away at the last minute time after time.
The pay off might be a better moment for WrestleMania, but the execution of Kofi Kingston's struggle has been way off. They seem more so like tricks rather than storyline devices used to garner sympathy for Kingston.
Kingston already has the WWE Universe loudly chanting his name on a nightly basis, so the sympathy for the character is already there. Anything more that is done to the superstar, whether to further the storyline or not, is just mean.
