He Should Have Been More Brutal
Now, by this I don't mean that the Miz had to fight fair. I quite like the idea that he was a cowardly champion who just survived onslaughts and found ways to keep his title. But there should have been more promos where he ambushed challengers and beat the living snot out of them. After all, this was a heel champion that wanted to be known as the most must see champion in WWE history. Instead Miz became a bit naff as champion because he didn't have the brutality of a lot of other heel champions, including JBL, CM Punk and Randy Orton. Miz should have been using every underhand trick to lay out the challengers and make himself seem like the sort of guy who would do anything to keep hold of that championship belt- after all, without the championship, he is not a must see champion.
