Blizzard has posted a blog on Ratings and Titles in Rated PvP, «rating inflation» and more!
Clarification on Ratings and Titles for PvP Dragonflight Season 1We’ve seen a lot of discussion about ratings in the 2v2, 3v3, Rated Battleground, and Solo Shuffle brackets over the past few weeks and we wanted to clarify a few points, especially about “rating inflation.” We have alluded to a “rating inflation” system in rated PvP before, but we’ve never explained what it is, how it works and why we like it.Rating inflation allows us to increase the “mean rating” over time. What is the mean rating? Well, it’s probably easiest to say that a player with exactly average skill will have a “mean rating”, due to how the math of rating calculations works.Players above the mean rating have above-average skill, while players below the mean rating deserve our love and support. Under the hood, rating inflation increases that mean rating over time, meaning that while at the start of the season an average player will quickly gravitate toward a rating of 1500, towards the end of the season their rating may rise to 1800.
Originally, this system was developed to counterbalance the effect of players who earned a high rating early in the season then opting out of playing the rest of the season.We feel like every PvP season has three stages:Early season — When most players are earning Conquest on a weekly basis to acquire gear. Mid-season – When most players are finishing their gear sets, gearing up alts, and trying out different classes.
End of season – When a lot of players are pushing for seasonal milestones or titles. Rating inflation was meant to ensure that the real action for titles happened at the end of the season.
