Whats the easiest and most effective DPS class to box in your opinion?

I've tried mage, shammy and hunter... i found that ever since they enable hunter to shoot and run at the same time.. they are really great dps that could dish out dmg while you run around.. not to mention the pets they have..

now i jus love em.. of cuz.. mage has portals and shammy can revive by themselves.. at lower levels.. sometimes my sv hunter top the tps in my team.. that's with a basic rot or even no rot for my hunter.. if the rot is properly set up.. i guess the dps would be quite crazy..

what dps class do u guys bring along? i am doing pally, mage, priest, e shaman and thinking wad to fill up for the last slot
