I remember reading somewhere that the true difference between a hardcore and a casual gamer is how much time is spent gaming but how much time they spend trying to accomplish the same thing.
I don’t know my hardcore/casual status, but I do know I am generally a fan of efficiency. So I was jazzed to find WoW in an Hour. I have yet to go back and look through all the posts yet, but I know I saw some stuff in the post about add ons that would be usable. Go see what would be useful to you.
