If you want to be a bear, it's gonna suck for a really long time. The trample bear is better for the first 40 levels or so. Around level 50 or 60, my pulverize bear started to kick ass, and now, at 85 or so, it feels pretty good. It's not as fast as my buddy's rogue, but it's pretty awesome just walking and slapping everything from across the room.
It's slow as hell as a bear druid, until it isn't.
