We're not even a week into the new 2.2 Patch (and the not-so-wonderful experiences we're having with it), and already there's talk of what we'll be seeing come Patch 2.3. Brilliant, imho. But at least the talk gives me something to read when Patch 2.2 KICKS ME OFF WoW!
One big change that we'll be seeing is the more player-centric PvP rating system. It involves rating players individually to go along with their team rating, and will be the deciding factor which allows or disallows players to purchase specific Season 3 items.
This change is a VERY good thing. I remember the days of PvP-old when missing a moment of the Rank 14 Honor Grind would completely derail your progression. While the current Arena Point system isn't quite that bad, your progress or rating can still suffer by means that are not in your own control. Essentially, people are being punished for something they didn't do, not something they did poorly. Thank goodness that's going to change. Thank you, Arena Point Sellers.
As for some of the details, you can read about them for yourself. I've got Honor to grind, and Battlegrounds to get disconnected from.
Enjoy your evening.
