unholy threat issues

[silbrev]

i have been tanking in unholy ever since i got my dk to outland quite soon after the release of wotlk, i tryed other specs after hitting 80 but didnt find them any beter just less fun to play.
Now as im reaching a good gear level im finding that my TPS is no where near what it should be i cant figer out what it is i would hope that blizz hasnt made it so unholy cant do enough tps cos i love the spec but iv moved the talents about in the tree loads of times and still its not good enough

any help would be much appreciated

Gear - The World of Warcraft Armory (http://eu.wowarmory.com/character-sheet.xml?r=Lightbringer&n=Silbrev)
Spec - The World of Warcraft Armory (http://eu.wowarmory.com/character-talents.xml?r=Lightbringer&n=Silbrev&group=1)

(my hit in that gear is low i have lower level bracer and belt to hit cap myself)

Gear looks fine.

In looking at your spec, do you really need "On a Pale Horse"? If you're having problems with threat, I'd look at dumping those points into another talent.

This is the recommended Hard Mode UH Survival Tree as quoted from Merko's Posting AOE Spec, MT Spec and Rotations (http://www.tankspot.com/forums/f14/40694-death-knight-aoe-spec-mt-spec-rotations.html)

Talent Calculator - World of Warcraft (http://www.wowhead.com/?talent#j0EroMhcZbxZbghcxczgf0o0o:MrA)

I'd take a look there first, and probably a couple other places on the forums. I know Krenian has some good posts that should be able to help you out.
