1. Triple H
It isn't like Vince McMahon and Triple H are beating each other up backstage, but there's a definite sense of tension between the pair. In July, reports emerged that they were at odds over the booking of Seth Rollins. Vince wanted the WWE Champion to be a more ruthless heel, while Hunter wanted him to be a cowardly heel. It is just one example of a creative issue they've butted heads over in 2015. At the start of the year, there was talk of them having significant disagreements on WWE's key directions. Again, Kevin Dunn relates to this point. He's in Vince's ear about how certain Triple H projects aren't quite right, and there's a bit of a "them versus us" aspect to Hunter's NXT and how it relates to Raw.
