I can't really imagine why you are getting hit for nearly double the damage of the warrior without seeing a WoL or at a minimum some Recount logs. I can see why you are soaking more overall damage, though. I am hoping someone else is providing the attack speed debuff and I guess you go kitty enough that having TF talented is worth it.
One of the glaring things I see is that you still strive to hit the exp./hit caps when these stats are far inferior to dodge. With vengeance and the OP that is Mangle (for now) hit and exp are just not worth it. Your dodge is really low since you have reforged to meet those caps. Take a look here http://elitistjerks.com/f73/t110351-...clysm_release/ and take note of the reforging recommendations.
