The bear does have some party trick DPS under the right circumstances that I just haven't been able to replicate on warrior. Like, when single tanking Windlord, the bear is typically top on DPS by a mile.
When accompanied in a ToT LFR with a pocket heroic raiding disc priest and surrounded by derp, the bear was tops on DPS for all the trash, Horridon and Council.
It does make me wonder if my warrior will result in a noticeable reduction in raid dps though. But then the warrior is using a 483 weapon right now, so I've only got apples to compare to my oranges.
