TFT - Round Matchup Mechanics Are Broken
The longer I've played TFT, the more information I track by game, and some I have begun tracking by round.
One of the biggest things that sticks out as NOT random is the matchups within a game.
I can post video after video from my time streaming TFT where, in a (relatively compared to the total community games occurring) tiny sample size of games overall, I'm repeatedly seeing instances of <3% things happening when it comes to round matchups.
There is no reason I can think of from a gameplay mechanics standpoint that a player should face the same player in consecutive turns until or unless they are four or fewer remaining, more especially when there are eight players remaining in the lobby.
There is a 1/7 chance of getting each opponent with eight players left. There's a 2.04% chance of getting the same opponent consecutively with eight players remaining. There's a 5.247% chance to get the same opponent 2 out of any 3 rounds. However, on a daily basis both instances occur.
I have personally got the same opponent's ghost four consecutive rounds with 3 of us remaining. That's a 0.39% chance of occurring. And that opponent's ghost isn't letting him take damage on four consecutive defeats.
The mathematics skew heavily away from the matchups within any sort of game being "random". I cannot conclusively say that there is any sort of "bracketing" (1 v 8, 2 v 7, 3 v 6, 4 v 5) that occurs, but there is an extremely high probability that there is some sort of backend algorithm that skews towards non-random occurrences going on, based purely on the mathematics.
If we're going to go into ranked seasons with this sort of shenanigans going on , it's going to be ridiculous, but entirely acceptable as one more variable to have to deal with.
But if we're going to see paid tournaments, as have already occurred, having any sort of backend manipulation of the matchups that isn't published would be something I'd suggest competitors be very wary of.
