My main is a 70 Druid that goes back and forth between Feral and Balance. I am able to use her to 5 box most outlands instances without any problem. Sure she isn't as good about AOE as a Pally and you have to watch things a bit closer, but you can't beat the Dodge, Armor and HP that they have. Where Pally tanking is pretty much a 3 button deal, a bear tank is maybe a 4 button deal.
