Blizzard released a new set of “crash courses” for learning various classes. Each crash course covers one damage dealing spec for each class. For the druid class, they chose moonkin. Thus, the video teaches you the basics of the Eclipse single-target rotation for people who have newly reached level 90.
The video does a great job of showing how Eclipse and our primary damage spells work. The video doesn’t, however, cover more of the advanced topics, such as what to do when there is more than one target. It also doesn’t cover talents and glyphs. These more advanced techniques are outside the scope of what these short videos were designed to cover. Thus, for more advanced druid techniques, Cyous has some videos, that while potentially slightly out of date may help fill in some of the advanced techniques. Cyous also took over the moonkin sticky guide on the official druid forums. You can also visit Hamlet’s EJ forum post. Icy Veins also has a moonkin guide.
Since Blizzard only did one starter guide per class, we don’t have a starter video for feral, resto, or guardian druids. There are, however, plenty of community resources to help teach you how to druid!
