16.6.1 Server Hotfix for Legend Rank Adjustment
Earlier today Blizzard made an announcement that they were doing a server-side hot fix to adjust the way ratings work in Legend rank after there was much to do about how slow and small ratings changes had become after the patch. The reason for this was that they had gone to a new, more precise rating formula that will be used in Battlegrounds. This is now being adjusted again to make it work more like the old way, while keeping the more accurate rating update formula in place.
Quote from BlizzardHey everyone,
We are currently rolling out a 16.6.1 Server Hotfix so that Legend players see a little more swing in their rank post-game. To prepare for the overhaul coming to Ranked Mode, we did some work behind the scenes with the 16.6 patch that swapped the old Ranked system over to the new, more precise, rating update formula used in Battlegrounds. This formula comes with a lower rating movement that happens post-game, which is why Legend players are seeing their ranks fluctuate less after a win or loss currently. This change should restore Legend rank changes to their previous state, while keeping the more accurate rating update formula in place.
We will continue to monitor these adjustments and make changes as needed.
