All I know is i saw this back when i joined in '09 and went, oh! I wouldn't mind playing a druid! (I like having a companion and buffing them and then seeing what can go down) but back then, it was a "oh, you can do fighter, cleric, rogue, mage, and we're working on the other core stuff. So hang tight!"
*refused to play... here we are 3 years later*
... I'm waiting.
