I think one round should have the same match time eg. Round One - TLC and etc.
I also think the first match should be a not-so hardcore match. I should write the One Fall (matches for the 1st round). To show we mean business, we should make a more-hardcore match as we get deeper into the tournament.
The tournament should include more people, and should in my opinion last till the PPV, so the match can be at the PPV.
