I think the problem is that even though these wrestlers are being pushed as hard as they are, they're nowhere near ready to hold a world title. After they're done feuding with all the top guys, they end up in this weird limbo where it's not their time to be in the World Title hunt yet, but they've already been established as being "too good" for the midcard, so they just float around and have meaningless matches, running over all the "real midcarders" and making them look like jobbers.
Ryback was pushed to the WWE Championship hunt. He turned heel, feuded with Cena and lost. But more than likely, WWE will have him squash a few midcarders to "get his heat back" and maintain the pretense that he's a big time player despite the fact that they still won't pull the trigger on him.
Why not bring in a new guy like Bray Wyatt, and actually give the low level faces a push to feud with HIM. Get someone like Alex Riley, and let him team up with a bunch of different allies like the Usos, Zack Ryder, Ted DiBiase, Justin Gabriel, Yoshi Tatsu, Tons of Funk, etc. trying to bring down the Family.
