A few questions reguarding Classes.

[Blackdog22]

Okay. I know I want to play either a Shaman, Bard, or Shadowknight. I love having multiple roles I can accomplish. My main area of focus right now is damage. I know Shamans can buff and slow, and Bards can Mez, buff, Slow(though not as good), Pull, and Shadowknights can Pull and Tank.

My curiosity is which one of these can effectively take on the role of a damage dealer without being laughed at?
