Also try and look my frost spec. It is pretty much the spec that is around on most frost tank trees. I however will say I am a blood tank not a frost tank. I just took my frost tanking spec from researching many of the top frost DK's on many servers.
the build seems good but it lacks some of the things i do like, such as killing machine but i made a mistake taking lichborne since it got nerfed very much(they removed the 25% reduced chance to get hit) and yea i need to get my jc up but its i friggin pain but anyway thanks for the feedback i will try and get a stam gem instead of the parry gem but the parry gem was way cheaper than the parry and i had little money after getting enchants^^
