Let's open a new topic up for discussion here. What is the best statistic in which one can make judgement on a players skill?
Ranked kill to death ratio, and win loss is nice and all, but ultimatey irrelevent. As if the ranking system is doing its job, most players should plataeue with a 1.0 KDR and 1.0 Win Loss as the matchmaking system starts to place them against opponents of equal skill. Even if you're within the top 10% of players, you should end up with a 1.0 KDR, and win loss, as your matched against people who are just as good as you are, within the top 10%.
What about the rank itself? I guess that's a pretty accurate testament to your ability, sometimes. Unfortunately it's very much skewed by the people who accompany you into ranked play. Your win loss is going to be much higher when playing as a team, than when playing alone. So that means a lot of solo, or smaller party players will have their rank undervalued, while those who party up will have their rank overvalued. Disconnections also do not register as a loss (which is stupid) therefore this data can also be skewed by people attempting to avoid losses, making it even less valuable. This is possible for all of the data in Siege, though I feel more likely to occur in ranked play where people take the wins and losses more seriously.
Outside of ranked we have casual statistics. Despite the name, I think these actually hold the most competitive value, the aforementioned reasons make ranked stats relatively, irrelevant (actual rank would be much more relevant if ranked was split between parties and solo, as it is in games like rocket league). But casual KDR, is usually a decent representation of an individuals ability that is relatively independent of whether they are playing with a good team or no. I certainly lose more games when I play alone, but I'm still able to retain a similar kill to death ratio, and that statistic doesn't plateau as a result of same skill matchmaking.
On this matter, on same games without a sufficient skill-based matchmaking system; Destiny, Call of Duty etc, anything above 1.98 places you into the top 1% of the distribution. While this in itself isn't indicative of competitive value in the more serious gametypes, I think it does indicate the players that posses the raw ability to be shaped into competitive players given appropriate focus on communication and strategy.
I'm curious on this matter as I want to begin grouping a good team together for ranked play and want to investigate what may be the best metric by which to sort players. So ultimately, I need to determine the statistic or combination of statistics that are is best predictive of ranked performance.
Would anyone like to share their opinion on this?
