That will likely be because Reigns wont be told to act like a dorky babyface anymore. Like it or not, we live in the post Austin/Rock era of cool more badass babyfaces. That door can't be closed now, people have seen it. So a traditional face like Reigns or especially Cena is seen as old hat and incredibly lame. What they should've done is book him to not be a dork. They can change things now and maybe that'd work - probably not, but I say that first impressions matter a lot. And this is the kinda crap they had Roman saying most weeks:
Other stuff:
Remember that "I can, I will" nonsense? People can't unhear that either. God damn that was lame.
There was the build to his match with Brock where he as the babyface did fuck all to get the fans on his side. Not one good promo from him, nothing. Top babyface - fuckin' please.
I could go on... but folks get the point. WWE (mostly) and Reigns fucked up royally, you can't pin the failures mentioned above on the fans.
