WoW's 7th Anniversary Wow, yet another year has gone by for WoW! We wanted to thank you again for playing World of Warcraft with us. With the return of a certian very large dragon, this has been a rough year for the world of Azeroth. On the other hand, that means heroes like you are needed more than ever. Get out there and defend a shattered world! The WoW Dev Team
