I've only won a few championships, but cannot fathom how desperate I would have to be to cheat to win one. I'm sure there has been cheating in GD as has been evidenced time and again w/ Tigerpark, however, I would rather quit the game than to have to cheat in order to win. I'm a proponent of Gladwell's 10,000 hour rule. I don't think that it takes 10,000 hours to be good at this game. However, I think those that put more time and effort into understanding how this game works, generally find very high success in their results.
