Rollins being terrified of Fiend and then losing to him cleanly was terrible booking. Of course it made Fiend very popular and got his merch selling. The supposed top face of the company looked like a wimp before him - as did Miz throughout their feud. He gets over at others' expense, and if he was a long-term top guy, that would have been fine. But he is clearly a novelty attraction best used in his own self-contained universe. If he keeps having Firefly Funhouse matches in the midcard, it's fine I guess.
