Yep I agree with that it should have been someone like Kane probably but I think they wanted to use the recent history to sell Cena's improvement (goes from barely beating Bray to destroying him ) it was the wrong call Imo but I see why they did it.
It seems they are trying like he** to keep Kane strong so Daniel Bryan can 'bury' him.
This talk about John Cena is going nowhere. There is nothing in Vince McMahon that seems to indicate he cares much about entertaining smarks.
If something, anything, makes money. It will be that something that will have precedence over any beliefs a smark may pull out of their a**.
If The Bunny began bringing and Vince knew for a fact that it could continue to deliver, he would continue featuring that character.
Cena is Vince's last star. Booking Cena as strongly as possible is imperative. Vinc'es investment in Wyatt is minimal, hence the lack concern on his part
