I stopped playing after Ahn'Qiraj to be honest.
Half of the guild left, some stayed. I believe this was when WotLK was released.
Logged back in again after like a year or something on AQ, I saw ONE player from old is fluffy.
Dont remember who it was, but he played as a mage and his name started with A i believe, he had other characters aswell that he played on.
