>>18365796Triple H is ultimately beholden to the TKO suits. I think he gets a lot of leeway in most cases, but whenever they step in he has to listen. I doubt he wanted Travis Scott there to fuck up Cena's heel turn and ruin the main event of WrestleMania. You can tell he was pissed about that whole situation.
More to the point, he's the head of creative and if he's letting the writers run wild, that's entirely on him.
