Screenshots or it didn't happen. I have seen ZERO crits above 6k and that only on a Sorc with no expertise gear. Posts like yours create the illusion we are still OP. For the topic, I feel like both specs are where they need to be. Vengeance can be beastly and doesn't require the set up that rage does, it also has more surviveability. Though not as fun for me.
Let no one mock the tank tree, it still has immense utility in huttball and the other WZs.
