I haven't seen a high quality Druid leveling guide out there. There are plenty, like..
Gaviilan's All-in-One Guide is pretty in-depth about the whole being a Druid thing, its just outdated (eg charm doesn't check cha).
Mefdinkin's Guide is a lot more concise but full of good info.
..those are probably the only two Druid guides on the wiki I'd reference. Druids really need a new guide for Velious, as there's so many more targets now for charming and quading.
