We were the JOINT least played class with Warlocks and sometimes Shamans dropped to as low as us but they usually climb up a % or 2 to stay above Rogues. (the class was always between 6-8%). Right now Rogues are almost 50% less than Warlocks and Warlocks r the next lowest class, theres been a massive change... therefore there is a clear and real fall in players playing Rogues and the data 100% shows this.
Basically the lowest played class has taken a massive hit in players and their population has dropped to epidemic proportions... the main problem with this is that such a small playerbase gives the class a very small voice. Nobody will listen to such a small portion of Wowplayers...
