If you would ask me, what would you like to return to WWE? I would immediately say bring back the King of the Ring Tournament. Not as a PPV like in the past, but as special episodes of Raw and Smackdown. I don't think it should be used as a PPV because there are already too many of them. Plus it gives us something else to watch instead of the weekly episodes.
The winner of it should be someone in the midst of a push, making him a bigger star, someone who has never won a tourney like this before and should be granted a Worldtitle opportunity at the next coming PPV.
How to book it personally?
I would book it between Survivor Series and TLC. Being a 16 man tourney. The opening matches and quarter Finals should take plave on the 30th of november episode of Smackdown and the Semi finals and the finals on the 3rd of december episode of Raw. Given that timing the winner and current champion should have enough time to promote the championship match for TLC.

Regarding my booking, it speaks for itself. I'd like to have Barrett win the tourney, beating Orton in the finals to end their feud of last year. Thus making him #1 contender for the WHC. Let's pretend that Sheamus is still champ by then. We can have a battle at TLC with Barrett becoming the new champion.
