Blizzard has finally revealed some details about the new Hero class for its new World of Warcraft expansion. As you probably know the new class is the famous Death Knight.
Details were revealed in the Q&A with designers of the new WOW's expansion. The new Death Knight class is yet another tank class as an alternative to Warrior. It will focus on attack rather then defense, and it will have the new Rune System to use for their "attack" magic skills.
The story goes that Death Knights have rebelled against the rule of famous Lich King Arthas, who is the key figure of the new expansion.
