Oh, i know that HHH has had plenty of diversity. From heel, to jokester, to tweener, etc. But nowadays, he's still hugely over, even though he's just another generic face right now. Off topic a bit, but if he can turn heel, it'd be great.
Anyway, I know you don't like Batista or Rey, because like we both said, they lack character diversity, but my point is, logically, that should allow Kennedy to be a main eventer, because even if you feel he lacks diversity, you can't deny he has more of it than either of those two, so if the standard of being a main eventer allows a guy like Batista or Rey, and the current version of Tripel H to main event, then surely Kennedy should meet those standards.
