The Rock holding the title for a couple months can't hurt unless he disappears again with it. If anyone else got the title off Punk now it would make him look weak. Give the title to Rock, then to Cena at WM then it can go anywhere from there. Preferably one of the Shield guys.
I think they should build up the actual tag teams like the Usos, PTP, Epico and Primo and Sin Cara and Mysterio more. Have Sandow and Cody split up and Kane should turn heel on Bryan. Then maybe Bryan can get a well deserved WWE title reign going.
