The guides and information above is so useful...it is also jammed packed! It has taken me several reads, different builds, and changing things up as I leveled to find what works. And I am still working on it! The coolest thing about being a druid is healing. You can do some decent dps, but the ability to heal a partner, stranger, group member, etc is awesome. Enjoy it!
ps..I think lightening strike is way more effective than swarm.
In my opinion, druids are the most flexible class out there. With the right build and equipment, we can heal, tank, dps, or buff others. But because we are so flexible, it is also one of the hardest classes to play. Finding the right build for different situations is very difficult, and that's why the guides here are so valuable.
Also, I like strike better than swarm too. swarm misses too much for me and suck up a ton of energy.
