Playing as a Blood Dk in PvP may seem easy, because it is. All you have to do is sit there and pound on the enemy and heal yourself up. Blood Death Knights have very useful Cooldown moves that make it even easier to survive in arenas. When I first hit 90 on my Death knight, I knew I was going to be doing arenas, so I knew I'd want to be Blood Spec right away since my gear sucked.. It was a great choice, even with terrible non-PvP gear on I was able to survive long enough for my partner to kill at least one enemy, if it were a 1v1 at the end, I was able to out survive the other person 9/10 times.
Here are the Stat Priorities you will be wanting to follow for the best results as a Blood DK in PvP:
Melee Hit (3%) > Expertise (3%+) > Strength > Mastery > Crit > Haste
PvP Resilience and PvP Power
Patch 5.3 introduced major changes to PvP Resilience and PvP Power to reduce their effectiveness. In general, traditional secondary stats like Crit, Haste, and Mastery are now much more effective in PvP. Our stat priorities are based on the best available information, but we expect our recommendations to change as the PvP season progresses.
Melee Hit (3%)
The Hit cap of 3% (1020 Rating) will eliminate the chance for any special ability to miss against other players.
The Expertise soft cap of 3% (1020 Rating) will eliminate the chance for your attacks to be dodged or parried by caster specs/classes.
Increases your Attack Power and the damage dealt by all of your abilities.
Mastery: Blood Shield adds an absorption shield with every Death Strike.
Increases the chance for your attacks to critically hit for additional damage.
Increases the rate of Rune regeneration and your attack speed.
Following these stat priorities may make it even easier for you to survive in arenas!
As far as Enchants and Gems go you will want to have strength gems for the most part, and also mastery gems. For chest enchant, you want either Stats or Resilience, Cloak Enchant you want crit, and for your weapon you want to runeforge it with Rune of Swordbreaking, to reduce your disarmed.
