Frostblood Tank

This tank spec allows you to control the damage you will receive as a tank which you are constantly doing as well as the threat of bosses and any mob or add the comes at you or your party.

First: Damage reduction, this is a good rotation of your defensive skills to give those healers a break when they see that you are only taking smidgens of damage.

1: Lichborne (3 minute cooldown)
2: Unbreakable Armor (2 minute cooldown)
3: IceBound Fortitude (1 minute cooldown)

This should allow you to use these skills constantly over the course of a battle.

Now threat control, AOE is the way to go.

(This is if you don't have the Howling Blast Glyph or if you have the item [Sigil of the Unfaltering Knight])

1: Icy Touch
2: Pestilence (skip if fighting a single target)
3: Howling Blast (or Obliterate on a single target)
4: Blood Boil ( or Bloodstrike to proc [Blade Barrier]

I hope this spec helps.
