Blizzard asked yesterday several players for assistance, suggestions, reports regarding bugs and other information that can improve the Arena Tournament Test Realm and with great success, as an impressive number of players responded.
Actually, Comunity Manager Hortus informed that they will change the realm in order to comply with the players' reports: "Based on observation and player feedback we will be making some changes to the TTR starting areas to make the NPCs more accessible to everyone. These changes may not make it into the next 2.4 PTR build update."
