In the Wrath of the Lich King, World of Warcraft will be introduced to its first Hero class, the Death Knight. Many players are anxious to play this new melee/casting hybrid class and experiment with the new talent tree. The class should prove interesting to play, as it offers several different options of play, including tanking, support, and even some off healing.
The blood talent tree focuses on physical damage dealing abilities and is well suited for tanking and sustained DPS on single targets. The Death Knight self healing also helps minimize down time, which makes it popular for leveling. At the higher levels this build will allow for several options in Raids as an off-tank or DPS role.
The frost talent tree is used for critical burst damage with focus being on spells and control. There are no dedicated Frost builds that truly take advantage of everything the build has to offer, with most builds including a mix of either Blood or Unholy Talents. A combination of frost and unholy talents work well for PvP, while those looking to tank should stick with a mix of frost and blood talents.
The Unholy Tree focuses on spells, summons and diseases, as well as PvP focused abilities. These also make for decent tanking qualities and hybriding for DPS builds.
The Death Knight should prove not only to be a mighty opponent, but also a very adaptable group member. Once the expansion has been out for awhile and players have had a chance to play around with different builds for various situations, we should start to see some standardized builds.
