Hi, I'd like to say I'm a pretty knowledgeable DK tank, I read up on everything and have looked at every possible source of information I could. The changes didn't look too devastating, but I decided to try out dual wielding frost. I have 41 expertise and have been parried three times by a boss in a 6 minute fight.
My problem is I got completely gibbed in the 25 man normal Trial of the Crusade by the first boss. He hits with impale and his normal hit, and I'm pretty much dead. I figured the boss was just really hard, so I didn't think too much of it. We went to 25 uld afterwards, and Razorscale took me to 1k health with one shot. It wasn't a crit. I'm really uncertain with what's going on, as I have roughly 8% more avoidance at the cost of 2k health, and I just got The Black Heart for the armor procs. Even with bad luck, there's no way I should be getting gibbed and utterly wrecked so easily.
I've got all new gems, and I've got my rotation down, and I use my cooldowns at appropriate times. I'm really not sure why I'm getting gibbed, as even if Blood is superior at the moment, the difference shouldn't be THAT vast. Could somebody please help me understand what's going on? Did they raise the uncrittable level or something? Does the difference in specs (blood's self-heals taking a lot of pressure off of the healers) make Frost much harder to heal? I could really use some help. (Armory isn't updated at the moment. Look in post for stats.)

Thank you.
edit: I don't really care if I have to go respec back to 2h blood, I just wanted to see if other DK tanks were having the same magnitude of trouble I am having. Not trying to complain or anything, just trying to see if I'm doing something really wrong or if the dw frost/2h blood difference is just that big. =)
Note: Gear I logged out in is what I frost tank in. Spec is DPS, since I did a test DW Frost DPS since I was pretty sure I wasn't keeping the DW Frost Tank spec I had.
Note2: Sorry for not posting in the other threads, I didn't want to derail and I have slightly (majorly, in most of the case) different questions and reasons for posting.
