So I'm on Gilgamesh and there are two people with near perfect scores. This of course wasn't done legitimately, but I want to try to break down the method so the information is out there for people to digest. Keep in mind that this is a working theory and I could be missing some details, but I think I get the gist of how people cheat this terrible system:
There is a set of algorithms that determines what a single TT player is "worth" towards other players. It's not straight wins. I've had a FC member win 34 times against Jonas of the Three Spades and lose his 35th match to me. This nets 105 points total (point shown before match starts was 97)
The top two people on Gilgamesh are currently at 35/35 wins and @ 4,647 and 4,565 points which means on average they are netting 132 points and 130 points per game, respectively. So clearly there is one or more variables at play to make you worth more towards other TT players. I have theories but no means to test them, I would assume that the most valuable players would be people who have played other "real" people and won. You could do the math on the round-robin number of people to get 35 people all with 34 unique wins against other "real" players, but it would probably be unrealistic for a single FC or person to achieve. So instead, what I am assuming is happening is the following:
Someone has a total of 4 accounts, 32 characters @ level 15 (I've heard that this is the minimum level to get to TT, but please confirm.) 31 characters are feeders and 1 person is your main. You can take the first person and have them achieve 30 wins from the other feeders and then finally feed that to your main character. The next person can do the same, only their record would be 30 wins - 1 Loss (from feeding #1). You could repeat this process over and over and I assume you would be somewhere near the average points per game of 130~132.
So really, if someone wants to buy 4 accounts and spend a few hours leveling a bunch of characters to level 15 and getting them all to the golden saucer, I could see this being not too much of a time effort. One of the two people that are currently at those point rankings were there by the time I woke up after the patch was out...yeah, I'm sure those were legitimate. To give a comparison, I will play a random person who has ~65-70 cards as well and win and get about 114~117 points for my win, nowhere near the 130+ required.
So yes, Square Enix, please overhaul TT tournaments, sooner rather than later because right now, it's not a tournament at all, it's who can buy more accounts and feed themselves wins. Not cool.
