You will always find a variety of knights, but none of them is as exceptional as the death knight. It basically has three levels, with the first one starting at level 55, which allows you to add on your points. What’s amazing is that if you manage to leave level 58, it will help you in working without necessarily having to visit the previous content of the old game.
Death Knights have the ability to fill two roles very well; that is the role of a damage dealer and a tank.  The two most popular choices for talent specialization are Unholy and Blood.  As a Blood talent specialization, you gain the ability to do large amounts of damage, and siphon some back to yourself as health.  This allows a Death Knight to continuously pump out damage with less worry about their health points.
Unholy Death Knights don’t have to heal very often because they usually have help with them in the form of zombies.  This zombie can be cast on creatures once they are killed and are great companions to a Death Knight.  If the talent specialization is done correctly, this zombie can be present nearly all of the time.
As a tank, Death Knights are the most deadly and difficult to take down in player versus player content.  They are much different than all of the other tanks – particularly Warriors and Paladins.  Much like the class of a Druid, Death Knights do not use shields.  Instead, they prefer two handed weapons that they are able to instill unique buffs onto through the use of their runic power.  They also have the ability to dual wield if they choose.
Death Knights also have many forms of damage mitigation, which particularly becomes useful when battling multiple enemies at a time.  They do not use rage or mana, but rather have a unique system called runic power.
Runes at some point appear a bit difficult to understand. The logic is that you need six runes with two of base type. The three major runes, frost, unholy and blood runes, can be sampled out in a special way. With frost and unholy, you can be in a position to successfully bring out the death runes, which count as, frost unholy and death runes. This basically offers you a unique opportunity when playing death knight.
One simple tip for you is to always remain cautious as you play death knight. Remember that they are exclusively unique and might not appear in any other way to be same as any of the classes that you have played before.
Be attentive to the levelling guide plus the quests as well, especially if you are a beginner. This will, in a much simpler way, teach you the basics of the game, and will further explain how to fully utilize the efficiency and pleasure that you achieve from playing death knight.
