Ryback is negative change. His catchphrase is the dumbest shit I've heard since Al Snow and the head and his gimmick is so Goldbergy Vince has to edit the live audience because they chant it so much.
Wade pretty much the same thing although he paid his due around the world and really has shown that he is the best of the nexus even above danielson.
And someone discredited his catchphrase, but every wrestling catchphrase is cheesy. For example: "Can you smell what the Rock is cookin'?" "You're going to feel the bang" "Oh hell yeah" "What?" It's not really what they're saying that matters, it's how they're saying it and what persona's presenting the phrase. 'Feed Me More' is simple, but it has a nice ring to it.
I know I'm late to the party as usual, but personally I voted for Ziggler. I know, I know, a lot of people are camping for Dolph, but from the choices given I'd like to see him get the title above the others. A close second would be Barrett - I think he's a strong performer, but since his return I haven't really felt much of an impact from him as far as his character goes. And it hurts me to say it - I really like the guy. Miz? Another character I like, but he's had the belt not too long ago - and had a lengthy reign with it. I can see him winning it again at some point, but I'm not sure how soon it will be. That and I feel that creative is still ironing out his face turn, if that's what it is. Ryback? No. He may be the "next Goldberg", but I just don't see him being "the guy."
Plus, I imagine how much heat Dolph would pull as WWE Champion. I remember that scathing promo he dropped on AJ... just think of the stuff he's going to say if he gets his hands on the title.
Taker beats Punk at Mania for the title but, Wade cashes in the MITB contract he wins at Mania on Raw the next night and becomes the new WWE Champion.
Realistically i see Ziggler winning the World championship soon and possibly Wade winning the WWE Championship.
