Would players with bad ratings be brought back up to the mid point if they sat out?
What's the point of having a good or bad rating? Do you get something for a high or low rating?
TBH there is nothing you get with having better rating except you can buy rated gear from pvp vendors. Most of it is for pride I guess. I think people's rating before 1800 or so will not lose rating, but after 1800 it kicks in.
