Druids are notoriously hideous to level until you get bear form at lvl 10. They are basically a gimped mage. After 10 you get a couple of levels of fun because it's so cool that you can turn into a bear, but you quickly realize it takes an hr to kill something as a bear.
Then level 20 and cat form arrives. And it's all good. You can stealth anywhere and kill anything, fast. You can shift into bear to deal with a seemingly infinite number of adds and can pewpew like a mage for different flavor. It keeps getting better -- at 30 you can run away from anything via travel form, at 36 you get a stun opener, at 40 dire bear form makes you almost unkillable, at 50 mangle makes you a dps machine.... So stick with it. It goes from the worst class to the best.
