The only way I agree with this happening is if Seth came back on some REAL heel shyt. Im talking having Sting jumped on site whenever he enters the arena like they used to do. Some legit cheating. You know just, really drive home the point that he isnt just some punk running his mouth anymore. They could have used this to have him start disregarding Triple H and cause tension there. When he starts thinking he doesnt need the Authority anymore he finally stands on his own. Fans no longer see him as a lap dog, HHH, Kane, and Steph aint all up in the video, Stings fans get to see something they thought was impossible. Everyone is happy
Sting has to be a transitional champ of course, but i dont see how it would have been a bad thing if they used it right. Seth was getting stale. Sting paid his dues and deserves it. The whole thing could have lead to actual character development, Hell as an added bonus if they used this angle to separate Seth and the Authority it opens up more possibilities with Ambrose and Reigns as well
