I do apologize about the wait here, folks. There's been a lot of contradictory information from both the beta and an array of Druid bloggers on how moonkin are shaping up for Wrath. While a lot of this is just the normal ebb and flow of changes in the alpha and beta, most of it is fueled by a few new talents and the set of glyphs that will become available. All of these have the potential to seriously impact your gameplay and rotation choices, so Balance DPS is going to be (at least, from current appearances) a lot twitchier and more proc-dependent than its counterpart in the feral tree. In addition, you'll probably have to make a few hard choices that will be affected by what your raid's going to need from you (although there is a truly amazing talent deep in the balance tree that, no matter what else you pick, is going to be a significant raid DPS contribution). As Balance is the only spec that I haven't gotten to raid on, I didn't want to go live with this until trying to figure out which pieces of information were accurate and which ones weren't. Bear in mind that Blizzard is still tinkering with Balance as I write this.
For the guide to feral in 3.02, head here; for the guide to resto in 3.02, head here. You'll probably want to be familiar with the resto changes, as balance has traditionally depended on a few key talents in that tree, some of which have changed. Otherwise, read on for a comprehensive look at balance's new talents, updated skills, and glyphs!
