So I have played WoW for almost 19 years and I am 99.9% sure this is false.
rating is not taken from the other player. as this would make no sense at the beginning of a season when everyone is zero and there is no rating to take. This is further wrong as there is rating Inflation added at the end of every season. you don’t lose more rating just because inflation is add…
Thus back to what I was stating, is players need to be rewarded based on how they play. This helps to keep players wanting to play the objective. And even if you lose, a Good player will always rise the ranks to a point where other they will compete with players at there skill level thus eventually getting the 50/50 or 60/50.
Currently the rating system is highly based in RNG with no way to really shine through.
