...Attitude Adjusted never picked John Cena, he picked JUAN Cena! Therefore, CM Punk would've versed someone who wasn't superman in the Quarter Finals, and would've presumably won the match, and the tournament. I demand a re-do!
Maybe for another tournament you could try a randomised one. 16 people sign up and are assigned a number from 1-16. I'm assuming there's still the option in-game to pick a random guy on the select a wrestler screen.
So for example, Masson is #1 and I'm #2. You randomise our match and he gets Kane while I end up with Santino. Every match would be randomised so we'd nearly always have a different wrestler throughout the tournament. That way no-one could say "so and so only won 'cos he had Cena."
