Hail and well met, Druids. For the next three Shifting Perspectives columns, I'm going to take a look at Druid class roles on Ulduar fights. If patch 3.1 hits earlier than expected (I'm currently betting that it hits in late April/early May), I'll try to squeeze these in a little bit faster than once per week. But with luck (and, I hope, a parade of annoying bugs for Blizzard to hunt down and squash before they let the patch go live), we should have some information to chew on before we set foot in a live Ulduar.
Now watch Blizzard deploy the frickin' patch next week.
I have not gotten the opportunity to test all of these fights personally because I'm only on the North American PTR, and some fights -- like Yogg-Saron -- haven't been available for testing at all. What I write here is going to be a compilation of personal experience, details concerning boss abilities available on the PTR version of Wowhead, information I've gotten from pestering various people on both PTR's, and news available around the web, principally from WoW Insider's previous PTR testing, Wowwiki, MMO Champion, and World of Raids. Bear in mind that some things here may wind up being very different when Ulduar actually goes live, so take numbers and conjecture here with a grain of salt. I'm going to assume that basic boss mechanics are likely to remain the same or similar, so let's get started with the first three encounters.
