I use to single box my rogue with a friends hunter and we would eat stuff up. His pet would tank it so I could backstab. I would think these two classes will have an easier time killing mobs then the rogue/priest combo. The only down side is you won't have a way to heal so if you haven't started herb/alch you might want to.

While I enjoy healing classes, I'm thinking about making a rogue/hunter team just for the fun of it.
