More bronze and silver divisions needed?
Lately I have been considering the skill differences between ranks and have found what I believe to be a major flaw in lower ranking match making. I will use perceptions of skill differences between higher help rankings to support this theory. High elo players reading this, keep an open mind about the actual skill differences that exist at these levels instead of blowing the idea off saying all low elo is equally bad.
If you ask most high elo players, the difference in skill between mid plat and mid diamond is huge. When you look at percentages difference of the player population, this is a mere few percentage point increase. This is because skill will vary according to a normal distribution curve in a population (think back to your high school stats and that's the giant hump of a curve where 60 something percent of the population lands exactly 1 standard deviation from the mean. That means that the greatest differences in skill will be found at the two ends of the curve (highest elo and lowest elo).
If a few percentage point increase in relative skill level at high elo can make a big difference, then it certainly can at lower elo.
If someone is bronze 5, they can in theory be matched with someone up to silver 5. Silver 5 as a division lands at roughly the average skill level for the league population. B5 represents the absolute lowest people on the standard distribution. We don't see a big difference because in our heads we think oh it's just 1 full rank increase. However if you were to use the other extreme where we match a silver 5 player with a mid diamond player, the issue becomes very clear. According to a normal skill distribution, the relative difference in skill between B5 and S5 AS A PERCENT OF THE PLAYER POPULATION is the same difference as that between S5 and diamonds.
Yet we don't match diamonds with silvers and a big part of this is how many divisions separate the two.
If we were to further divide bronze and silver into 10 divisions each, we would create a system that would be much better at matching players by their relative skill level over that bottom 50% player bin.
Please offer feedback and pass this on to a rioter if you happen to know one.
