Druid as a whole is an under powered class at the moment.
Here is mine. The post includes other informational links.
As far as I've seen, generic feat setups tend to be as follows (assuming human):
Wolf Dps: Toughness, Maximize Spell/Empower Healing, Quicken Spell/Power Attack, Shield Mastery, Improved Shield Mastery, and Natural Fighting (x3).
Evoker: Toughness, Augment Summoning, Extend Spell/Empower Healing/Heighten Spell, Empower Spell, Maximize Spell, Quicken Spell, Spell Focus: Evocation/Mental Toughness, and Greater Spell Focus: Evocation/Improved Mental Toughness.
Bear: N/A
I've haven't seen any pure bear tanks out there, because 1) The 28 point first-lifer isn't going to be able to get their intimidate high enough to matter to pull a boss, 2) Their dps won't be anything special either. There are a few multi-class builds out there like 12 Druid, 6 Fighter, 2 Rogue/2 Monk that have potential if properly geared.
