Erm, Death Knight is a lot easier to handle than the BM.Blademaster is pretty underhanded, but easy to stop.
For me, its the Death Knight.
Agreed.Tauren chieftain easily. His ultimate owns everything, it's almost like huskar's ulti, fine it does 20% less hp, but it deals MAX hp instead of current hp, and does it to everyone in AoE, which is huge.
