From the blue post:
Just highlighting this to ensure that everyone is aware that the rated phase has now concluded. Any games that are played outside of the rated phase won't count towards the pet or title reward, so you can't gain credit towards either of these anymore.
Just so you know though; the realm will be sticking around for a while yet, so you can definitely feel free to sign up and play some epic PvP action!
Hope you folks got your games done in time!
