Notes and Useful Information: 

• Hit rating effects both spell and melee hit. The recomended +hit for PvP at lv 80 is 5% (164 rating) since that is enough for al your special abilities (strikes) to hit the the target. Two hand raiders should run 8% hit (263 hit rating)

• Strength is basically the main stat for deathknights, since it gives attack power and gets extra benefit from multiple talents. Because of this, it is always better to socket for strength instead of attack power. Your ghoul also gets extra benefit from your strength.

• Agility only increases melee critical strike chance as well as all special abilities aside from: howling blast, icy touch, and death coil.

• Expertise from talents give 0.25% chance to not be blocked or parried per point. 8.20 expertise rating is equal to 1 expertise, and 4 expertise is needed to reduce the chance to be dodged or parried by 1%. At the end 32.79 expertise rating or 4 expertise points from talents is required to reduce your chance to be dodged or parried by 1%.
