If you play less than all 9, please specify why.
If you only play a certain spec, or exclude a certain spec, talk about that too.
As someone that has always played all 9(or 8 before HoT) classes for one content or another, I never quite understood why many people don't. Alting is easy enough in this game. Help me understand. I mean I understand why you would exclude 1 or 2 professions if you just don't like them. I have those too but I do maintain a character for all classes anyway.
