mcgozer: Maybe the people who run this game need to update their published information. I don't sit and pour over these forums for information that should be published in plain sight. As I said, I pay money to play this game, I think its not asking too much for the rules to be clear and available. What follows is what is published.
Nobody expects you to pour over the forums. The point I'm making is that maybe you should realize there are the aspects of the game that you're simply unaware of before making any claims about what is possible or impossible and who or who may not be cheating.
Over the years, WGT has been clear that they don't publish the criteria for tiering up. I suspect they never will. But players have figured out the process of tiering up through ranked rounds. Even so, that criteria changed a while back. For example, the information you copied and pasted is outdated.
There is now a Tour Champion tier. The number of minimum ranked rounds for Tour Legend is now 750 rounds, and the number of rounds for saturation at Champion tier is 1,000 rounds.
None of this has been published by WGT and (again) probably won't be published. The players figured it out.
Finally, no where has anyone stated that the information you copied and pasted is the only way to tier up. I believe players have been able to tier up to Legend through match play. It's been that way since I've been a member. Coin matches is just another method.
