I can see the dislike towards Gunther as champ. I like him with the belt, but I can see how others would think he can be boring. Yes, he's great in the ring, but he hasn't wrestled nearly as much as he did when he was the IC champ.
Hell no to Jey with the belt. He's just over with the kiddies with a dumb catchphrase and style. He needs to head back to the tag division which is on life support as it is.
If crowd reaction is what we're after, I recommend re-strapping the rocket to Dom. Has he been injured? He really had all the momentum and it's been totally cut off. He'd get nuclear heat as champ (yes, I know it wouldn't make sense for him to wrestle Gunther, just work with me here).
