I've been Blood for most of my leveling and life has been sweet to my Death Knight. However, I realize that Blood focuses a lot on physical damage since Death Strike and Heart Strike are both physical attacks, like Mortal Strike or Crusader Strike, compared to Scourge or Frost Strike from the Unholy and Frost talent trees.
My question is, does this warrant a talent respec? Is the DPS increase worth the lack of self-healing? How is the survivability using Frost and Unholy? I tried leveling up a bit with a Frost build, but having been used to Improved Rune Tap, Improved Death Strike and Bloodworms, I didn't like that my health went down and didn't get back up automatically.
What's your take on the builds in PvP scenarios (mostly Battlegrounds)?
