WoW newbie looking for advice

[Warlock]

Oh my god Cat Form is incredible. Most targets of my level (20) die under 10 seconds. Just ... no words. :blink:

Actually, after using the Bear Form for a while, it feels like I've been fighting with both hands tied behind my back, and now somebody finally set me loose.

Glad you're enjoying the Druid. It's a great class (though the others each have their strengths also).
If you like Cat now, you'll love it after getting Pounce in the mid 30's. It's a stun and a bleed in one.

In general Bear can handle tougher opponents than Cat but not as quickly.
