Win-trading prevention in Gold Saucer Tournaments

[finalmattasy]

If there were diminishing returns in matches for those that play the same pc over and over, I think that win-trading could be almost eradicated. So long as the, "repeat opponent," penalty is strong enough; those that trade, if not banned from playing entirely, will be forced into trade groups, which would be tougher to maintain.
In this scenario the real players will no longer have to deal with those that cheat with their singular cheater friend, often taking top prize in the process.
Another way would be to lock matches to new opponents only. Essentially in a 30 match tournament, even if there are only 30 players on a server, force everybody to play everybody once.

To combat trading from a player side, starting a Gold Saucer Linkshell (like I did) is a great way. It makes it easy to get opponents. Report traders too. There's no need for cheaters to get top prize all the time. I hope Square does something about this. I'd rather see an empty tournament than a fake tournament. On Behemoth, I don't think it'd be empty.
