Rating issues for Arena and RBG wins
There is a strange issue taking place at the moment with rating. Rating itself is a tricky thing to wrap your head around, especially as it's recently gone thorough something of a shift. Right now, your character has two ratings for every bracket of arena, and for RBGs. One is the MMR, the matchmaking rating. This is the rating the system uses to match you up against similar level players. It's shown at the bottom right of the scoreboard after every match, as an average of your group's character MMRs. The other type of rating is CR, Current Rating. This is the rating that your character earns by winning and losing matches, the one that's shown in green and red letters in the main part of the scoreboard. It's also the rating that gets you titles and mounts. Every season CR is reset to 0, while MMR remains what it was last season. So, if you ended season 14 on an MMR of 1800 and a CR of 1880, you'd have begun season 15 with an MMR of 1800 and a CR of 0. What happens next is that as you win games, your CR increases towards your MMR. You should expect it to stabilize as you reach a CR that's near your MMR. As you win and lose games, your MMR will also shift. Your MMR aims to give you a 50/50 win-loss rate, as when that's achieved you're being pretty evenly matched.
Bornakk on arena ratings changes
Apparently there's been some confusion over the exact way that the new arena ratings changes work. Bornakk tried to clarify that a bit today. As he tells it, The adjustment to a team rating will always be based on the other team's team rating, but the adjustment to the personal rating of everyone in the match will be based on the average person rating for the other team. He used the following example:
