as a leveling feral druid I found that when I was at the mid to upper level range of a bracket I did fairly well. AS soon as I hit 60, well the brick wall found me and things changed when all the other classes got gear that scaled and I, well I got shafted. I still miss the PvP set bonus though, the speed increase was just sexy.
With my balance druid in PvP when I am not stuck defending I score pretty high in to categories because I actually know where my heal button is, and just short of 1k spell damage in PvP gear hurts a bit.
