I have a druid who I heal, tank, and cat dps with and I find myself having trouble keeping what is good for which separate in my head. Having to refer back to the different threads on EJ is annoying though. So since I apparently need to write the information down somewhere, I figure that I might as well do it here in case it helps others. Plus if people disagree with anything it can be discussed as well. This won't be a full write-up of things, but rather just things I need to refer back to for the various specs. It'll also have some biases in it for the way I know I play and the content I'll be likely to do.
