WWE need to create a lot more non title feuds to create an interesting midcard on all the shows, they need to remember that the mainevent feud can only take up so much time and they do need to entertain us for the rest of the show.
Christian is being wasted at the moment. He is an excellent performer and can feud with anyone, I would be using him against a Ziggler or Barrett. It will be a big win for those two younger stars and Christian will be able to help them a lot. Dolph Ziggler really does need another big scalp, after going over Jericho, to be seen as a legitimate contender in the fans eyes. Randy Orton would have been a good option for him but Orton beating him cleanly on Smackdown kind of defeats the purpose of a feud between them.
I would like to see a feud involving Sin Cara/Rey Mysterio and Cody Rhodes/Damien Sandow. Cara and Mysterio have a reason to team together as they have both been targeted by Cody Rhodes who doesn't like those that wear masks. Rhodes and Sandow are a natural pairing due to their eloquence and apparent intellect. Would be a good clash of styles and a good way to use four very solid hands. I don't neccessarily think they have to work tag team matches all the time but it would be a good way to utilise them all.
Wade Barrett needs something good for when he makes his inring return after a long injury layoff. He should face off against a big name so that he is thought of as a maineventer right away rather than just another midcarder. I wouldn't mind seeing them going back to Orton/Barrett again because that produced some good matches. Barrett taking apart Big Show for breaking his arm would be a good feud but for that to work one would probably need to turn face. I just want to see Barrett beat Show clean.
Ryback. He needs a proper feud soon to really move his character forward. WWE have done well to start feeding him actual WWE midcarders rather than random jobbers but the next step is an actual feud. What about Tensai vs. Ryback? The matches would be a bit ugly and the promos non existant but still it would actually be an impressive victory if Ryback managed to defeat him.
