Is there a class that can clear dungeon when 5 boxed?

Being macroed out the ying-yang makes hunters really easy and fun to box and very, very strong. With my 5x paladin team, they were not particularly effective - they could take 3-5 mobs (slowly, with pauses for healing) and be OOM halfway through, whereas with my 5x hunter team they're just tearing through stuff. Granted, still low levels, but now that I have my pets it's pretty ridiculous how effective I am.

With a dedicated healer in the mix, you could effectively dungeon grind. You might even be able to dungeon grind without a healer, but there will be a lot of battle ressing pets, tossing a mend and throwing them back mid fight I'd expect.

I'd also suggest, try bats for screech, since it's a mini demoshout, it might generate a moderate bit of aoe threat, or, run all wolves for stacking constant furious howl which should buff the overall dps of your puppers and hunters significantly. I'd actually put them into your dps rotation, on round robin, to prevent overlap!
