According to Google trends, AJ has more interest currently than everyone barring the veteran main eventers such as Cena, Orton, HHH etc. More than the Shield, Alberto Del Rio, Daniel Bryan etc. She deserves much more air time and to be apart of males storylines.
1. Cesaro with Heyman as his mouthpiece heel
2. Dolph Ziggler as a face
I wouldn't want to mega push the Shield as singles guys yet, I'd rather see them hang together for another 6 months or more. But once they do, I think Roman should be pushed as a WHC contender as a heel, Ambrose for the IC title as a heel, and Rollins for the WHC as a face.
