Is it worth Ziggler winning the WHC?
This isn't me hating on Dolph, I like the guy and think he has loads of talent. But will anyone actually buy him as world heavyweight champion? Every time he goes into a big match, you're 99% sure he'll lose. He's nowhere near credible enough to be the World Heavyweight Champion in my opinion. And if anything, if he wins the title he'll probably lose the title to Del Rio again in a month or two then go back into obscurity.
Another route that the WWE could take is to have Ziggler cash in, only for Del Rio to steal the win. At this point, AJ and Big E could turn on the despondent Dolph, and it is discovered that AJ and Big E have been banging all along, with Ziggler getting sympathy from the crowd and then turning face. Ziggler and Langston could have a good feud based off this, and a powerhouse like Big E could make Ziggler look like a real underdog face, especially considering Dolph's selling.
After this feud, Ziggler could work his way back up from rock bottom all the way to the top of the mountain, this time without any shortcuts or distractions (e.g. Vickie, AJ, Big E) and later down the line Ziggler can win the title off a big heel (e.g. heel Orton)
Long story short, is there really much point in just making Ziggler the WHC, considering that the WWE will probably still not make him look that credible and drop the title in a short space of time? Or would it be more beneficial to go a different route with his character? Right now he is not looking like WHC material (in kayfabe terms, of course)
