#3 Not great on the microphone

The WWE Universe seems to want to prop up Seth Rollins as some kind of god on the microphone, but that really isn't the case. In fact, one could argue that Rollins' success on the microphone comes down to his ability to connect with the audience and not from his ability to find zingers or say something truly impactful.
One only has to look to Seth Rollins's corny segment on Raw about pointing to the sign and about this being a dream his whole life to know that he isn't exactly on a CM Punk or Dean Ambrose type level. Its also obvious that there really isn't much impact in the words he's saying, which is another thing that is bothersome during his promos.

WIth that being said, he does pretty well at playing off a crowd, but he will never be the Dean Ambrose or CM Punk that fans try to prop him up to be. Then again, his heel persona is probably the closest he has gotten to coming on that level of a talker, but his babyface character is very lackluster on the microphone.
