#3 Carmella.

It's no secret that Carmella was never going to set the world on fire as Smackdown Live Women's Champion, but deserves a lot better then what she is doing right now. While heel championship reigns are usually plagued by ridiculousness like this to help draw heat, it runs the real risk of hurting Carmella in the meantime.
Not only was this feud already dead on arrival when Asuka lost relatively clean to Carmella at Money in The Bank, it was also taking away the focus from what should have been a relatively refreshing championship reign. Again, probably wasn't going to set the world on fire, but she was capable of playing a heel relatively well.

In the end, it's sad to see time being wasted on this, but its even more sad to see Carmella's reign plagued by this nonsense. She deserved so much better than this and the longer it goes on, the worse it's going to be for Carmella's chances to be the blue brand's top woman. Its also going to diminish her star power, which could leave her in freefall when it is done.
