Preface:

After a week individual work without WoW Circle team, we realized that our cooperation has been productive and we do not represent competition for each other in mind different rates, we decided to continue working together for as long as possible.
Team WoW Circle will focus on PvE content and operability of the game mechanics, and we are part of PvP, so PvE respectively fixes a little earlier will appear there, but pvp fixes here.
I think of this, we only win and make up even more serious competition to other servers MoP, which recently appeared very much.
