With the WotlK NDA crushed and thrown away there's an information upheaval. WoW Insider is sorting through the overload and what will set WotlK apart from TBC is the Death Knight. It's the first new class introduction since World of Warcraft launched in 2004. Sure, there is some cause for concern. The big question on many minds is will the class be over powered? If you aren't in the beta maybe the following three videos will help you decide. Each video showcases a different talent tree: Unholy, Frost, and Blood. The videos are courtesy of Leiah, WotlK beta tester and MMOG blogger at World of Feedback.
The video above displays the Death Knight thrashing around in the Pools of Aggonar and specialized in Unholy. What stands out is the Death and Decay, a powerful AE ability, which leaves a wake of destruction in its path. When used in conjunction with Corpse Explosion and two Blood tree talents: Butchery and Vendetta, a lethal combo ensues as each kill returns 6% health and 20 runic power. Lichborne, Bone Armor, and Death Gate are also used. You can also see the sacrificial ghoul explode and deal 2,000 extra damage. The other two Death Knight build videos are after the break.
