well tbh op you are talking shit,christian is a excellent worker and his matches with Orton were some of the best matches of that year,He was fucked up booking wise during his reign as wwe had no faith in him.
So you don't want him near the World Title because WWE booked his reigns like shit? But don't worry OP, he won't be near the World Title scene again.
Anyway, I think Christian should return and feud with Cesaro over the US Title. They would put on great matches together, and ideally I have Christian win the title from Cesaro at Mania, ending Cesaro's long reign, Christian wins the US Title - a title he's never won before, plus he's gets a win at Mania which he hasn't had since WrestleMania 20, and Cesaro moves up the card so everybody wins.
The best thing Christian ever did was his series of matches with Randy Orton. He proved he could hang as a main eventer. Of course, I don't ever want to see Christian as champion, but he would be a great challenger and have good matches with John Cena, Alberto Del Rio, Sheamus... etc.
As a heel, of course. When he's a good guy, he's worse than Chris Jericho. Some people should stick to being permanent heels...
Nah. While those series of matches were great, The best thing Christian ever did was his Captain Charisma character in late 2004/2005. Best character in wrestling at the time. He's a better heel for sure, but he's a good face too, not sure what you mean with the ''when he's a good guy he's worse than Jericho'' comment, Jericho's a good face and he's one of the few wrestlers, like Christian, who can pull off both roles very well.
