I got into the beta a week ago (and with the last Annual Pass wave, a lot of the rest of you should be, too).

But errors are odd things, and I found I could cast Immolate all day long on my destruction spec.
So I did destro for a day of questing and flinging fire at the training dummy. Here are a few of the first thoughts I had.
