Mmm, does anyone boost with Hunters, Rogues, or Druids?

Hunters: pet can tank, pretty much sic pet, fire and forget. No real AOE, slow.
Druids: stealth runs, tanktastic, very slow DPS, can heal.
Rogues: stupid fast DPS, stealth runs, no heals, very minor AOE with Blade Fury.

What I'm thinking so far, Rogue beats the other two for boosting, as the rogue will be burning them faster than anyone else, and everyone will be taking pretty low damage already, since we're not talking about massive pally pull boosting.
